I occasionally get another 'I' word - irritated - by my UFO's.
Mostly because they get in my way or have exactly the right fabric for another quilt but are already half-sewn into a UFO. But not intimidated. Life is too short to let inert pieces of fabric make me feel guilty. I'll finish them or I won't. If I don't finish a UFO, it's because I started a new project and I must want to finish the newer quilt more.
If I never finished anything, then I would let the UFOs upset me.
