I use the totes for DVD's. They have a handle, are flexible, hold a lot of fat quarters and have a handle for carrying. They are also pretty cheap and can be stored easily and keep your fat quarters clean. They are visible, clean, easy to handle and you can see what's available without even opening the case. Check out all those "unwanted" catalogs because they almost always have them. Just make sure the square size is large enough - usually 5 1/2" to 6".
