I would not toss, unless you have made an actual scrappy quilt and decided you don't care for them. If you do not want to bother then I suggest you offer them to someone on here who would like to have them, or perhaps someone you may know who also makes quilts. To me, a scrappy quilt looks best with lots of very small pieces. I know that takes lots of patience and time, so I would suggest just working on it a little at a time, perhaps in conjunction with another quilt.
