I had several boxes of craft stuff that hadn't been touched since moving to Texas in 1989. Back then I used to do a lot of counted cross-stitch and plastic canvas stuff. I donated 4 large boxes of craft things to a girl scout troop and several boxes of cross-stitch books, cross-stitch fabrics etc to another group.
About the only thing I wished I had kept were several pieces of the plastic canvas to use in the bottom of tote bags. Of course that stuff is cheap enough, so I don't mind if I end up buying a few more pieces. The only "craft" activity I do is quilt, and I'm happy to have purged all of the craft stuff that hadn't been touched in eons.
