The shades are a great idea ... wish I'd thought of doing that. I use book shelves too, with the fabric arranged by color. To protect from dust and fading, I just made some full-length muslin curtains with rings on the top making it easy to slide the panels out of the way when I want to access the fabric. I used plastic bins for a long time, but it was too difficult to find what I wanted. Vertical storage takes up just a bit of floor space, and I can see all of my fabric at once making it easier make color choices.
