What to do with incomplete vintage patterns

Hi all, I have quite a lot of incomplete vintage sewing patterns. Too many to post. I don't want them and was wondering if anyone knows what I might be able to do with them? I'm not sure my local charity shops will want them with them being mostly incomplete, and I feel bad throwing them out, but at this point im just keeping them for no reason...

Hi, My only suggestion would be to send them to a fabric shop that uses old patterns as wrapping paper - I know 1st for Fabrics do this, there are probably others too
