Are there any you started coz it sounded like a good idea but now you really don't want to finish? I ran across some items like that recently and sent them off to one of the charity groups on the board. Instead of beating myself up over yet another project not completed, I know the bits went to a good home.
Are any of them in grocery sacks? It may be self-denial but UFOs in bags become PIGS. Just don't count them twice.
