I got mine at a comic book store. $9.00 for 100. Just waiting for more to come in. They are wonderful! You can see all your fabric, without digging through a tub, or pulling a whole stack off your shelf to get the one on the bottom. Fabric looks so pretty lined up on the shelf.
I have not quite figured out what to do with my fat quarters though........still trying to come up with an idea for them.
