Here's what I think. Pull out the projects you have in bins, partially done, kits that you have never started. Then look at them with honesty and say "Will I finish this by ______________ ? (In my case I would put one year but that's an individual thing) If the answer is yes, then have a great time. If the answer is no, then look at the project and ask yourself if the project and somebodyelse would be better served if you passed it along.
There are many many women on this Board, at community centers and at churches that do charity quilts.
To me, an unfinished project that is sitting in a bin for years is sad.
