d20 Handbag of Holding: How to build it Now thats a Dice Bag!
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.
