Sewing a Roll-Up Canvas Bow Case

 

 

These instructions are for a case for a two piece take down longbow, and should work for a bow up to 68". Obviously, many shooters do not shoot this type of bow. The measurements can be readily adapted for use with a 3 piece bow. Simply measure the longest limbs you will put on it and add 6". This will give you the width measurment for the large center panel. It will allow 2" for the seams and 2" extra at each end of the limb pockets. Use the center section, which is used for arrows here, for the larger riser. If your limbs are recurved, rather than longbow, you will have to adapt the pocket size accordingly. If you make separate bow socks for two sets of limbs, you could use this three pocket design to hold the riser and both sets of limbs. Alternatively, you could adapt to two pockets for the riser and one set of recurve limbs. Don't be afraid to make adjustments to meet your particular needs.

 

 

 

I recently built my first take down bow, using the Connexion hinge system. I followed that up by using the same system to convert an existing bow to take down. ( See: Take Down Bow ) When I finished the first bow, I built a very heavy canvas case for it. In fact, the marine duck material I used was so heavy I couldn't handle it in my small sewing space. My 1926 industrial treadle sewing machine would sew it, but it was so stiff I couldn't keep the feed right and I lacked feedout space for it. My wife's business is marine upholstery and sewing, and she has the shop and equipment to handle that sort of thing, including a much heavier machine with power fabric feed and a 45 sq. ft. layout and feedout table, so she ended up sewing that one for me:

 

 

 

 

 

 

 

All of my excitement was about my first take down bow. However, when I posted the pictures and included the case, everyone said, "Nice bow, but that case... Wow!" So, I promised that when I made the case for my second take down, I would make it out of a lighter canvas that home sewing machines could handle and that I would do a "case-along" to show how to do it.

I just finished that case, with lots of pictures, so now I'm building my "case-along" presentation. I'm going to start by assuming that most guys aren't real familiar with sewing. Sorry if you happen to be a retired tailor, but I think that assumption is going to be true in more cases than not, so I'm going to start with some sewing information aimed at the inexperienced.

Most trad guys are used to some kind of shop work. Sewing is really not that different. You need some basic familiarity with how the machine works. That's usually covered pretty well in the machine's manual. Basically, it has two threads, a top thread and a bottom thread. As the needle goes down, it carries the top thread through the material and makes a loop below the platform surface. There's a "hook" underneath, and each time the needle makes a loop of the top thread, the hook pulls the bottom thread through that loop and the needle then pulls the top thread up again and repeats the process, making stitches. Good sewing requires the proper tension on the two threads. The tension has to be adjusted, or set, as appropriate for the thickness of the material being sewn.

Your manual will have pictures of good and bad stitching, but basically, you look at a test seam. If the top thread is pretty visible as a line on top, then the top tension is too heavy, it's pulling the bottom thread up too much. Reduce the top tension until the stitches appear as a series rather than a line of thread. If the bottom thread is pretty visible as a line on the bottom, then the bottom thread tension is too heavy and you need to either reduce it or increase the top tension. When you can see a nice series of stitches on both sides, then the tension is good and the stitches are connected between the layers, where you want them.

Aside from getting the machine set right, which is no different really than setting up a table saw or band saw to handle the material you're going to feed it, half of the battle is handling the material. In that respect, the sewing machine is no different than your shop machines. You have to understand the seams needed to make what you want (think of them as cuts in wood) so that they will feed into/through the machine. The big advantage to sewing is that while you can't unsaw a cut in wood, you can rip out a seam and redo it.

You need to know that when you start a seam, you press down with a finger on the loose thread ends so they don't snarl. When you end a seam, you put the machine in reverse and back up over three or four stitches. You're lucky... your machines will have reverse. My antique machines don't, but I know ways around that that you don't need to worry about.

One final word... in addtion to the sewing machine manual, many (most?) of you have another valuable resource... a wife who sews. She can show you the stuff I've talked about faster than you can read it. You might even be able to con her into doing the job, but she won't be happy about the heavy material and you'll miss a lot of fun and satisfaction.

OK, lets go...

Material and Initial Layout/Cutting

I bought cotton canvas duck fabric from JoAnn's. They had a good selection in a lot of colors. I considered pink, but settled for this nice macho brown. It's going to appear as both light and darker throughout the pictures because my camera couldn't decide when it needed the flash and when it didn't. Don't let that throw you. This fabric is 60" wide on the bolt. You should be able to get the case out of two yards, but I got three. I don't like to skimp. I also got four yards of 1" nylon web strapping and a chalk pencil for marking. I got a package of 1" brass D rings from Tandy Leather. These are optional. I thought they looked neat, but velcro as I used on the first case works just fine.

I should note at this point that just because I chose to use canvas doesn't mean that you have to. You could use pre-quilted quilt fabric, available by the yard, an old blanket, or whatever you want that you think will serve the function of protecting the bow and being sturdy enough to last.

You're going to make the case out of three pieces. The main piece is a rectangle 38" by 44". The other two pieces, which will be the flaps that fold over inside, will be trapezoids 19" deep by 18" at the wider side and 14" at the narrow side.

At the edges, the fabric off the bolt will have what is called "selvedge". This is a narrow tight woven strip at the edge to keep the fabric from fraying. You will be laying out your pattern to make good use of the selvedge so that you won't have to make your machine try to sew through doubled over seams. More on that as we go.

 

 

This is a close up of the selvedge at the edges of the fabric. You can see how much more tightly woven the fabric is on the selvedge edges.

 

 

Spread out, 60" fabric is big. I laid it out on Ann's cutting table, selvedge to the top. You can use the floor, a piece of plywood over two sawhorses, a ping pong table... whatever you've got. I then used a chalk pencil and laid out my 38" x 44" rectangle, which you see here. I laid in seam edge markings 1" from the bottom and both side edges. No seam marking is needed at the top, or selvedge edge

.

 

Next I cut out a strip 18" wide. This will make the two trapezoidal flap pieces. This strip will have selvedge at each end. The wide edge of each flap will be at the ends of the strip, so that the wide edge of the trapezoid will be selvedge. Cut the two ends of the strip off at 19".

 

Put the selvedge edge at the top. Find the center and make marks on the bottom edge at 6" and 7" from the center.

 

Brace yourself. This picture and the next one are optical illusions produced by camera angle! You're just going to have to wrap your mind around it and trust me. The material here looks like a trapezoid. IT ISN'T... it's a rectangle. The camera makes the farther away top look narrower than the bottom. We're going to make it a trapezoid, though. I've drawn lines from the 7" from center marks on the bottom to the top corner, and another line 1" in from that. These are, again, 1" seam lines.

 

OK, I've cut off the wedges at the sides. Camera angle now makes what really is a trapezoid look like a rectangle. This piece actually measures 18" at the top, or selvedge edge, and 14" at the bottom. It's 19" deep.

Note: I didn't get a picture of it, but you will want a 1" seam line drawn on the bottom, as well. No seam line is necessary on the top, or selvedge edge.

 

Here are the three pieces taken upstairs to my sewing room and laid on a smaller table I use there.

 

Now you need to start playing with your sewing machine, as described above. Use the wedge pieces you cut off of the flaps and set your tension.

Seam on the left has too much top pressure. You can see the top thread lying on the material surface. Seam on the right I tried an adjustment but wasn't happy with it, though it's lots better. Middle seam was getting there and I adjusted again about halfway down and you can see that toward the bottom of the picture I'm getting a nice stitch.

 

 

 

Folding Seams and Making Corners

I marked 1" seams where seams will be needed. The actual seam will end up being 1/2", because we're going to fold the outside edge in to the mark, then fold again before we stitch it down. The seams are necessary because without them, the fabric will fray and ravel... not nice. The selvedge edges will not ravel, so we are taking advantage of that.

 

 

I wish now that I had seamed the big piece first, since it has square corners, and I wouldn't have had to show you this little step first, but I didn't. I did the two trapezoidal flaps first. On these, you will make seams on both sides and on the narrow bottom edge, but not on the top edge, which is selvedge. I mentioned above that what we will do is fold the edge into the 1" mark (see next picture) and then fold it over again. Because there is an angle to the edge, this results in a sliver sticking out. I chose to cut off a small corner on an angle to eliminate this. You can see the piece I cut off here. Do the fold and you'll see what I'm talking about.

 

OK, here you see me folding the edge in to the marked line. You then fold again.

 

With lighter material, I'd pin the whole seam line. With this heavier canvas, that is not easy, or necessary. The fabric is stiff enough that if you "press" a fold in it by running a pencil down the edge, you'll find the seam fold is well marked and easy to control.

 

What I've shown so far is just fine for long seams. However, they meet at corners. This leaves you with a choice. With lighter material, I just let them fold over each other. With seams folded in as I've shown, you have three layers of fabric in each seam. If you're machine is happy to sew over six layers (many are not), there isn't a problem, and that is what I normally do on my quilts. However, with this canvas, six layers is a lot of thickness, so I wanted to use what is called a "mitered corner". The reason I don't normally use these is because I am lousy at doing them neatly. However, they are nice and I'm going to show you how to do them. I very highly recommend that you practice several on a piece of scrap canvas before you do one on your case.

The basic idea is that you fold the corner up at a 45 degree angle and cut off the tip. You can then fold the corner over and kind of make a seam within the seams where the two sides meet. The trick is cutting off the right amount so that the end result is neat. I don't often get it perfect, but this is a bow case, not your daughter's wedding dress...

 

The first couple of these I did, I started the seam and sewed until I was close to the corner, then dealt with mitering the seams. After a couple of poor ones, I started using more care and folded and pinned them before I started.

This particular one worked out quite well, so you can kind of judge how much to fold and cut from these two pix...

 

The two sides nicely folded in and pinned.

 

 

I've sewed down one side and am about to fold the next side in to cross over. Obviously, this was one I hadn't pinned.

 

Second side folded in and I'm ready to start the seam on that side. On the ones I pinned, I didn't have to stop the seam. I just turned the material and kept going.

 

After I completed the seams, I went back and sewed over the corners. This one was separately sewn seams.

Here is one where I sewed one side seam and then just turned the material and kept going on the other side seam.

 

 

As you can see, this one isn't as nicely aligned.

 

 

Here is a finished trapezoid folding panel... three sides seamed, selvedge edge at bottom.

 

 

The seams are easy, the mitered corners are a bit tricky, but if you practice a few, you'll be fine. As I mentioned, I did the folding panels first, then the large main piece. Once you have seams on all three pieces, you're ready to begin assembly of the case.

 

 

 

Assembling the Case

 

Once you have your three pieces all seamed, you're ready to assemble the case. The measurements I am going to give you assume you are building for a two piece Hill style longbow, because why on earth would anyone shoot anything else? If by some strange chance you do shoot something else, you'll want to set the pieces on the panel and make your own measurements. Seriously, these should work for all two piece longbows, including (I think) reflex/deflex. See the panel at the top for suggestions regarding three piece takedown longbows and/or take down recurve bows.

 

 

At the selvedge end of the main section, draw three lines... one 4" from the end, another 6" from that one, and another 4" from that one. These are the lines you see here.

On the seam edges, (incidentally, the seams go to the inside), make three marks... one 3" from the last line, one 4 1/2" from that one, and the last 3" from that one. These are the three marks you see on the edge above. You make these marks on both sides. Draw a chalk line between the marks.

 

Now place one of the folding flaps on the side of the main piece. Put the selvedge edge of the panel INSIDE of the seam. You're going to sew this piece on with two lines of stitching, but made inside the folded seam of the main panel, so that your sewing machine will only be sewing through two layers of material.

Position the center of the flap at the center of the 4 1/2" section you just lined out in the previous instruction. You should find that the flap is roughly 4" wider on each side than the last three marked out sections.

 

 

Pin the flap in position...

 

and sew it down with two parallel lines of stitching on the selvedge. Note how I have rolled the material so that it will go through the sewing machine's somewhat limited space. If your machine is happy sewing over the folded seams, you can do so, but it'll be fine to just start at the folded seam on one side and stop when you get to the seam on the other side.

Obviously, repeat for the other side.

 

 

Fold the bottom (selvedge edge) of the main piece up and pin it along the top chalk line. Try to line up the marks on the edges of the main panel with the lines drawn on the folded part of the piec and insert some pins along these lines. The spaces between the lines on the part you folded up are wider than the spaces between the marks on the flaps. This is to make tube space for your bow pieces and the arrow tube. Stick your bow pieces and your arrow tube in the pinned spot and try to see how they feel.

 

 

Uh, oh! This bottom bow piece tube is clearly looking too tight. OK, feel the other two "tubes" and adjust your pin rows until you're satisfied. I ended up with a bit more folded fabric than I needed. My arrow tube is still pretty loose with both limb piece tubes a nice easy fit. I think this came about because I used the same measurements here that I did on the first case, which was of about four times heavier and much stiffer material. This material had more give to it, hence, more total space for fit. This isn't a problem for me. I'll find a slightly larger tube for the arrows and it will comfortably hold my rolled up Lakota quiver with arrows in. Alternatively, you could sew a second seam about 1/2" from each of the center seams that hold the arrow tube, tightening that section and perhaps making the case roll up better. Interesting thought...

 

 

Here's the case laid out with everything in it.

 

 

I lay my glove, the string and a brace in...

 

 

and fold the flaps over. Note that because the flaps are sewn on inside the seams, and because they are a bit wider than the space they have to cover, they close up the tube openings, so that pointy limb ends don't try to slither out some open edge.

 

 

Adding the Necssary Fastenings

The final step in this project is to add a handle, tie straps to hold the roll, and, if wanted, shoulder strap rings. As mentioned at the start, I bought some brown 1" nylon web strapping and some brass D rings. I thought the webbing and D rings would look great with the brown canvas. If you don't care for D ring fastening, use velcro.

There are five pieces of sewing for this stage, and they may actually be a more awkward than the seaming and joining you've done so far because the pieces are small. My machine has no reverse, and I wanted points for neatness, I had to actually turn the whole project under and through the sewing machine, with the needle down, to get the stitching I wanted. This is no problem on the outboard side, but inevitably, you end up with one spot where you have to shift the whole mass of material under and through the space under the arm. If you're not looking for neatness, you can just sew back and forth using your machine's reverse. You'll see what I mean in the pictures.

 

 

This seems like a good place to show you the machine I chose for this job. (I have 30 some machines to choose from!) This is a Singer Model 15, circa 1915 to 1920. The treadle frame is an industrial size one that is completely restored and fitted with a wonderful industrial size working top, for maximum area. It will accept either home size machines like this one, or full size industrial machines. The black plastic panel at the left of the machine comes out to lengthen the opening for the larger machines.

 

 

OK, we are going to fit five additions... a handle, two tie straps, and two D rings on the ends to accept a snap on shoulder strap. These pieces are made from the nylon web strap, which is heat cut to the lengths you want. You're not likely to have an electric heat cutter, but a soldering iron or the heated up blade of an old butter knife will work fine. On the handle, the ends are folded back under, so that the sewing is actually on two layers of webbing. On the end D rings, you again have two layers, simply slipped through the rings and stitched down.

The tie straps are loose on both ends. On one end, the strap is slipped through two D rings. The other end is simply the burnt off end of the strap. They are sewn to the case for about four inches.

 

 

Roll up the case with the contents inside and figure out where you want the handle. You don't want it right on the end of the material. Here you can see that I have positioned it such that there is about 3/4 of a roll of material past the handle to roll.

 

 

Here's a shot of the case opened, showing the positioning of the attachments. The D rings for the shoulder strap are even with the placement of the handle. The stitching for the straps is actually past the handle, closer to the edge. You can see the chalk lines where that stitching started and ended.

 

This shot shows my positioning of the attachments from the inside

 

Here I am stitching the shoulder strap D ring. The webbing is doubled and I am stitching a square around the inside of it. I stitched down one edge, left the needle down but lifted the presser foot and turned the material around the needle, lowered the foot again and stitched across, repeated the turning and stitched down the other edge, repeated the turning and stitched along the edge of the D rings.

If you look a bit further back you can see one of the straps and how I stitched it. Again, a stitched square (rectangle, actually), turning the material. The actual stitching covers about four inches of the the strap, leaving a short loose end with the D rings, then the longer strap to go around the case.

You can see here what I was talking about when I described getting all the material under the sewing machine arm.

Now, if you have reverse on your machine, which you most likely do, instead of that turning, you can just stitch up and down the area where I made squares... but it won't look as good.

Practice on some scrap webbing.

 

 

For anyone who is not familiar with D ring fastening, here is a quick review. Two D rings are attached to one end of a strap.

 

The other end of the strap is fed first through both D rings.

 

Then the end is fed back through only the second D ring. When you pull the end tight, the strap is quite secure.

 

If the flapping tail bothers you, tuck it under.

 

 

 

 

Here's the finished product. You may note one error... I actually should have sewn the straps on in the opposite direction, so that the tails pointed down when you are carrying it. This is relatively minor, and as you saw above, I can tuck the tails in. If it bugs me too much, I'll take out the stitching from the back and resew them, but that's probably one of those things I'll never get around to.

 

 

I'm very pleased with this case, even more so than with the first one. I hope that some of you will give making one a try. If you master this, you'll be a little familiar with a sewing machine and maybe want to take on other projects, like wool hunting shirts or capotes.
