Do you have an active Craig's List or Next Door or something like that? I've connected many people to fabric that way, either by watching for Wanted ads or by offering them as Free. Before we moved there was a request for free quilting scraps. The person turned out to be a textile student in the age group where there were lots of friends having babies.... she happily took all my flannels, boxes of scraps, and some larger things like batting, basically filled up the hubby's small pick up truck!
When I first started purging my sewing room I decided I wasn't keeping any non-quilting fabrics and a different textile student took all my non-quilting off my hands and out of my space.
