Tie them and donate them to a local childrens home, VA or nursing home. From the looks of the stacks of fabric, there's plenty there to use as backings. Either that or check with local churches, quilting guilds, etc. and see if anyone would be interested in finishing them for charity. If there's a women's prison anywhere near your area or a disability services organization they also might be interested in finishing them for charitable purposes. Here there's Senior housing facilities that people give paint supplies, craft supplies, or sewing supplies to and they use them to give the elderly people something to do.
