I'd love to see where you store your fat quarters! Do you put them in a drawer? On the floor?
Here's a picture of what I did with mine... I found 2 letter sorters at a thrift store and stacked them. They are the perfect this for fat quarters. I took this picture last year, when I first started organizing my stash. It's nearly full now, I should take another picture.
At the very bottom, you can barely see the tops of my comic book cardboard. I use that to fold the fabric that is too small to fit on a bolt but too big to to fold into fat quarters size.
