|I just saw a very unique and great way to 'catalogue' your fabric stash!
Using a three ring binder, purchase picture slide plastic sleeves (they hold actual photo slides and are 3 hole punched); Cut small swatches from your stash fabrics and insert one into each slide pocket. You can use one sleeve for a a particular color, fabric types, etc. However you want to sort and display your swatches. For bigger swatches, purchase baseball card holder plastic sleeves. They hold larger sized swatches that will give a better visual if you have a larger type print.
While the initial set up of the binder might be a bit time consuming, you'll be able to take your binder when ever you shop and have your entire stash at your fingertips for matching up and coordinating!
PS - the slide sleeves hold about 40 slides so you'll be able to get great mileage out of a few sleeves!
