Like some of the others, I am cheap and use the clean pizza boxes and label the outside with a stick on label. They fit under my bed very nicely since I don't have a sewing room. I get them from my local Casey's store and so far they have been free of charge, but I would gladly pay the twenty five or fifty cents as well. I have used them for the cut blocks, quilt blocks and partially finished quilt blocks. There is no end of uses one can use them for. I have even put fat quarters in one until I got a three drawer stand on sale at Wally World. I also use the little plastic boxes mushrooms, etc., come in. Wash them up and keep them on the table for scraps when I am sewing and a jillion other uses from time to time. Have even put the smaller cut quilt squares in them to store as well until I pull them out and use them in something. My two cents for the day.
