I know this is about finishing quilt tops, and getting through UFO's. I would also suggest selling them. There are people out there, that hate to piece but love to quilt. That would buy the tops just to finish them.
When my original machine died. I had to wait almost a year, till I got my new one, If i had the oppurtunity to buy a top I would have. I looked, but people really don't sell them. Just a thought.
