A solution for this is to pass the work on to someone else. But it's mainly just to get them out of your mind in some way.
I frequently send my pieces like this off to Christopher and he'll do the same. So recently Christopher completed a set and he just didn't feel like they were somehow finished so he sent them to me. He asked that I add something to them. But when I got them I really liked them the way that they were and wasn't inclined to really add anything more to them. So they sat around until just now and Katherine and I used some of them to print over.
