I like your trashcan idea. I currently throw mine in a plastic laundry basket, a cute metal laundry tub (if I can find one) would work for me. It's not like I would have to carry it around, I just have to dig thru it. When it gets full, I cut scraps down to usable sizes 5" sq, 2 1/2" sq and then a big zip loc for those odd size triangles that are too good to toss.
