Recently, I spent some time organizing my stash of quilting fabrics by making "mini-bolts" using comic book boards.
Here’s a before, with fabric in five horizontal stacks…
Now it’s easier for me to pull out one or two fabrics without making a mess of the whole pile.
Smashed Peas and Carrots has a tutorial on how to fold the fabric to fit. It’s really easy, and the results are so neat and tidy looking. It works well for fabric at least 1/2 yard long, up to a few yards long. Here’s a link to the comic book boards that I used. I’ve blown through two packages of 100 already!
