I do that too. But my rolls are usually strips left over from each quilt. It really comes in handy when you are looking for a specific color or fabric. Since it was used in "this quilt", it is in this roll, etc. I had a quilt top I made a few years ago and wanted to finish. When I pulled it out to quilt, it just needed something else. I decided to add applique to the corners and partial border, so I just pulled out the roll that I used in the original quilt. So much easier than digging in my stash for all the fabrics used.
