Finish piecing the liner except for the last piece. Leave it loose so that you can turn the bag right side out. Design - This project just uses lots (20) of triangles. Find the height, width and area with lots of maths and stuff and determine how much fabric you need. In addition, most advertising networks offer you a way to opt out of targeted advertising.

MATERIALS: Red fabric, white fabric, red thread, white thread, needle, stuffing (I got mine from two pillows), PVA glue.

Piece the canvas together before the liner, as the liner is more flexible and doesn’t need to be as exact. We’re making a pattern and kit for this project available in two sizes: darling and practical. The tiny one is just over three inches tall, and holds little things for you. The larger size is about five inches tall and will fit your phone, wallet and keys along with your dice. By popular request following the d12 bag, here it is: the d20 bag! Now you can make your very own icosahedron. Once you have both done, it will be time to pin the zipper in place between the canvas and the liner. The zipper should be aligned fairly deeply so that the seam goes just below the intersection of the triangles.Our kit includes twenty canvas pieces, twenty iron-on stiffener triangles, twenty cotton liner pieces, a cord for the handle, a zipper, and iron-on numbers 1-20 in the lovely font BPreplay. The iron-on numbers are made from a cotton-poly blend which fuses as it is laser cut so that it won’t fray. Assembly takes a few hours and requires thread, needle, scissors, pins and an iron (for fabric, not solder). A sewing machine will make some parts go faster. Sew - Sew the edges of the insides of the triangles together. This step is pretty much described in the instructable link above. For orientation and placement of the numbers, its easiest when you have a d20 to model off (which I didn't at the time). It is possible to look at pictures off the internet and work it out from there too (which I did). There are two sizes of iron-on stiffener panels: little ones (eight of these) and bigger ones (twelve of these). The little ones are to allow clearance for the zipper. The standard allowance the sides of the triangles is about a quarter inch for the tiny bag and about three-eighths for the handbag. The smaller stiffeners that go next to the zippers have the same allowance on the two regular sides, and an additional quarter inch on the zipper side.

If you’re using your own materials, the small pattern is available here (26 kB PDF) and the large pattern is available here (24 kB PDF). The small bag takes a 9″ zipper, and the large bag takes a 14″ zipper. Depending on how you lay out your pieces, you’ll need about two square feet of fabric of each type, with a little less needed for the smaller bag. Once the zipper is in place, close it and mark the triangle intersections with pins on the lid side of the zipper. Corners - The nearly finished die (with one edge incomplete to turn inside out later) should have the corners stitched by hand a few times, just to make sure holes don't appear in them and stuffing leaks out. Next, begin sewing the lid together. Start at the open end and sew toward the intersection at the zipper edge.Lay them over the sewn strip (on the non-zipper edge), overlapping the edges and sew straight across the whole batch.
