I keep my projects in clear boxes that measurer 12X12 used for scrapbooking .They cost me $3.00 a box at my local craft store. I keep my finished blocks and the material I am using for that project. I also like them because they are clear and I can see the the project and they are stackable too. I am sure if you looked up scrapbooking supplies you would be able to find them if not pm me and I will see if I can get you the company name Happy Quiltin!
