I did it. I bought 4 plastic tubs that have great tops and stack. Two hold darks, one mediums, and one lights. Of the two I already had, one holds all flannels (they are arranged in strips, squares, rectangles...) and the other has pieces that are already sewn together in some way (extra trianlgles into squares, etc).
Then there's the tin I have all all extra quilt squares I didn't need for whatever they were made for.
I'm going to take the advice from the website Yvonne posted on my other thread and cut some of my smaller stash pieces into strips. I love working with strips. :D
Here's how it looks.
