I also use clean pizza boxes to store finished blocks in as well as cut pieces waiting to be pieced.
Plastic boxes for precut squares so I can grab a box of whatever size I need. Really neat for making four patches
I like the idea of pizza box size to store blocks in. I'm going to try to find something of similar size only in a clear plastic. I like the idea of a flat box.
I have everything else in clear plastic anyway. Here is a few, I have 8 other plastic containers, but you can get the idea from these.
Keep the ideas coming.
