Just donate the pieces and be done with them if you aren't inclined to want to work with them.
I've been given various pieces or squares. I tried to make a coordinate quilt out of most of them but sometimes, I just had leftovers. This is what I did with them.

I think the lady who took it as a charity quilt preferred the back, but here she is!

She chose this quilt from about 30 quilts!
