If you'll really never use them again, then give them away to someone who will appreciate them or to a charity.
But they may not match at first, but once you accumulate some more, there will be enough for a scrap quilt. I keep mine in a large ziploc bag, and have them subdivided into smaller groups there. I have a baggie of 1.5" squares that I'll probably never use.
You can follow Bonnie Hunter's lead (quiltville.com I think). She cuts scraps into widths of strips, and squares, then makes scrap quilts. See web site for suggested sizes.
