Hi, I used, I think, about the equivalent of 40 jelly roll strips. I bought my strips from connecting threads and they come in much smaller quantity...depending on how many fabric patterns in a line. The nice thing about the 1/2 hexi is you can make it whatever size as there isn't a specific block. Aside from taking forever to cut out, it went together fast and easy. 1 Thanks hisgrace1 thanked for this post
