I found one UFO that was 30 years old.. its the only UFO I have and most likely will never finish it... it has no appeal to me now.. and I can't bring myself to finish it. It was before I had a rotary cutter and the piecing is not something I would be proud of today.
When I was growing up my Mom would never ever allow us to cut any fabric if there was something unfinished. This "training" has stayed with me .
