I use pizza boxes, clean ones I got from the eateries. I store my quilt blocks in them. I have several boxes for different projects-in-progress. I put a big note on the top naming what quilt blocks are in the box. One box has the picture of the quilt. Makes it nice when the mood hits for which project to work on. for my fabrics, I have the bins, color separated and label also on the top and side.
