Since you didn't state what kind or how large the pieces are:
wallets, keychains, potholders, glasses cases, coasters, small wall hangings, cell phone carriers, book covers, book marks, mini-quilts, table runners, samplers, toss pillows, changing pads, stuffed toys, water bottle holders, trades/swaps.
That's what first came to mind. I'm sure there's a wealth of other practical suggestions to come. Whatever you make, please post a picture to share.
