I have several plastic totes are about 13" square and about 3 in. deep from Joanns. I get them on sale for 50% off. They have a handle and they stack up nice. I can fit all the pieces and parts of a large quilt in it, and have room for basic sewing supplies if I am on the go. When I run out of empty totes, then that is my que to get busy and finish up some quilt tops.
