If I'm doing one with say 2-1/2" squares, I'll cut several wof strips, then cut those strips into squares, separate by color into ziploc bags and put all the bags for that quilt on a book ring in the order I'm going to stitch them together, along with a final bag that has the thread for that quilt, a pack of needles, a seam ripper, and a small pair of scissors. Makes it very easy to take anywhere I might want to go and have everything I need to hand piece my quilt. Usually I have to go back and cut more strips/squares several times in the course of making the quilt, especially if it is a large one.
