I also use ziploc bags for my quilting pieces. Then I punch a small hole in the top of each bag and hold them all together, in the order to be stitched, with a metal bookring. The final bag is the thread to be used in the project, extra needles, folding scissors and anything else I can think of I might need. It all fits nicely in a tote along with the project in progress...even a queen size quilt top.
