Take a look at the link on the side bar and see what you can do with them? There are many groups wanting your Un-Finished-Objects or UFO's as we quilters call them. They can be fabric you no longer like, orphan blocks left over from a project, quilt tops or anything inbetween.
I know that I get a LOT of donations, usually from someone whose mother just passed away and they don't know what to do with her stash. My group, Vacaville Binky Patrol takes these boxes and bins and turns them into quilts for kids.
There are other charity groups out there looking for your UFO's. Check out the button and help some kids or adults who need a quilty hug.
