I keep mine in Sterilite tall plasic containers that I get at Joann when the everyday plastic storage is on sale at half price. They hold quite a lot of patterns. I have 8 of them, because I have over 1000 patterns, and they each hold different types of patterns, like piecing, applique, Christmas, etc. The boxes have handles and the lids snap onto the bottom, so they are easy to move around and stack.
