Wendy, you have me beat. I have vowed to not buy any 2.5's for any reason. I have gotten into the habit of "religiously" cutting my scraps and trimmings from any current project into 2.5 squares or strips. Lordy, I have thousands! I keep mine in zip lock bags by color, novelty and Christmas. I then toss the ziplocks into a large bag the size of a gym bag. Sorting them initially is a pain in the rumpus but once done it is relatively easy to keep up with. Happy sorting by the pool in the shade!
