there are many guilds that do a lot of sewing charity quilts. So offer some to them. Also, there are a lot of those thrift shops that provide work for folks or raise money for veterans or whatever, Neatly bagged fabrics, and other craft supplies will usually sell quickly at those places. They might not fetch a high price....but they are gone from your space and some shopper will be happy at the "find" they got. I know a few people who also look for such items when they go to the thrift shops. We also have an "artist" district in our town that is teaching a lot of different crafts including one that teaches basic sewing to young people. Give a call to some of them and find what they can use. They may even be willing to come and pick it up from you if you have it boxed or bagged for them. Finally, if nothing else....my neighborhood puts a lot of stuff out at the curb with a "free" sign on it....and it is usually gone that day or in a few days.
