I’ve seen craft tools and other bits and bobs kept in various bags, plastic boxes and pencil cases. None of them felt fun or versatile enough for me. I wanted something that had enough compartments to be organized, could open up so I could see what was where, but could still travel in my knitting bag. I began folding paper, origami-style, until I came up with a simple, long envelope pouch with a nice triangle structure to it. Four of these triangle pouches make a square, and the lovely symmetry of it lends itself to being rolled up! I realized if I attached each pouch to the backing with snaps, I could take the whole roll with me, or unsnap and take just what I needed.
