From time to time, I go thru my stash and see if any fabrics just don't "zing" for my anymore. If so, I pull them out and bag them up to take to our local non-profit thrift shop. Figure let them sell it to someone that it does "zing" to or let their group of quilters make quilts out of it. This way I'm using up my enormous stash and helping out others in the long run. I've got more than I can use in my lifetime anyway. I know some of my fabrics are at least 15-20 years old.
