Consider sharing your blessing of a big stash it with other quilters. I have discovered in my guild that there are a number of quilters on limited budgets or retired and on fixed income who love to use "hand-me-down fabric". One turns every thing into quilts of valor and the other teaches 4H classes for budding quilters. It clears just a little from my stash, but it is an easy way to help someone who I know will use the fabric well.
I also recently went methodically through my stash and took out all of the fabric that I knew I would never in a million years put in a quilt. I took it to a quilt retreat in two big Rubberrmaid bins labeled FREE and .... I took home two empty bins. Some was used immediately that week-end and some of the final odds and ends went to someone who makes rag rugs. OK with me. It will turn that fabric into a useful piece for someone and not just sit in the bottom of a bin.
