I do the same as QuiltingDragon, except I don't cut 4" or 4.5", but the rest of the sizes I do. I also have a 10" square pile, which really comes in handy, too. I stack them in those sizes on shelves that have glass doors, so I can see what I have. When it comes time to make a quilt, I pull out the appropriate sizes and start sewing. It's lovely not having to stop to cut out pieces before working on a quilt! I set aside the scraps that I have from larger pieces that I've used, and when I wake early some mornings (usually its 1 or 2 a.m.), that's the time to cut those down, as its a quiet activity. Before I had enough for the shelves, I used the clear shoe box bins to store the various sizes (5" and down). Didn't take long and I was looking for open shelving to stack the various sizes. Seems like they multiply like bunnies sometimes...I've made large quilts and it didn't look like I'd taken any fabric out of there!
