Our dog ate Beneful at one time, and it comes in these small plastic containers. They are great for storing anything small! I have several filled with small scrapbooking supplies, but just pulled out another empty one that I'm going to use to store the cams for my ancient sewing machine. I'm constantly knocking them on the floor.
I love all the suggestions here. In a few weeks, I'm moving my craft room upstairs, totally reorganizing it and making this room a formal guest room. I'm looking forward to using some of the suggestions - especially the one about the design wall on sliding closet doors! Which makes me think of another thing I'm repurposing - the flannel back table pad for my dining table is currently being used as a design wall...ok, design table :) I need to figure out how to mount it without ruining it, since I still need to use it under table clothes.
