Organize Stash
I had my fabric in deep shelves like that and found I didn't like it as I couldn't see the fabric in the back. I just had stacks of fabric one in front of the other. I now keep mine in book shelves and I can see all the colors I have.
If you figure out how to do the Piano hings shelf could you please share as I would love to see how that works.
Happy Quilting!
