We're supposed to finish these things? Is there a time limit?
Actually I can boast of finishing all my quilts. All five, over a period of 20 years or so.
Now tell me. How do you remember what you were going to do with those UFOs and PIGS? (Leave notes, as I sometimes have done?) How is the initial enthusiasm regenerated? Where in the creative process was the project suspended? Do we drop breadcrumbs along the way? Where in the world are they put while awaiting attention?
These heavy issues burn deeply into my psyche, and I'd rather finish the dang thing than deal with "issues."
In reality, I have one WIP that's in danger of becoming a UFO if I don't get out there to my workroom right now. Then there'll be six (count 'em, SIX) quilts FINISHED.
