I've done this more times than I want to count. The upside of all those UFOs is, that a few months ago when my quilting group was making quilts to send overseas to a church mission group, I found 3 UFOs that I didn't like but thought they'd be great for a child. The downside is that I only managed to finish 2 of them so the third one was picked apart, restyled and half finished probably to sit like that another couple of years (and I still don't like it enough to finish it!).
