I store my fabric by the quilt project. Which is how I usually buy. I keep a cupboard of orphan fabric, and pull that fabric into other projects as the new projects come along. Since I like the autumn, and civil war colors mostly, I have a lot of fabric that works for many of my quilts. Every once in a while, I'll do more of the summer/spring colors, but more of the deeper, darker values. So they work with many of my quilts as well.
