Oksewglad: Cute mini and what a great idea to put a magnet on the back!
I know what you mean about getting the sorted piles in the right spots! I have mine divided for church quilting and Bundles of Love. I do use some of the church donated fabric for Bundles because our church leader just wants it out of her house and used wherever!

. Most of the tub fabric will be re-donated.
