Ahoi, matey! I recently started to focus working on one thing at a time. OK - it turned out to be two but only because I didn't have the right color thread, so I made some blocks while waiting for the store to open.
IT FELT SO GOOD when I FINISHED the small wallhanging yesterday. I mean FINISHED. Binding on, label on. Now I am on to the next UFO. Gonna kill me some Sunbonnet Sues today. lol
Just pick one of your UFOs. If you thought it was worthy to start, it is probably worthy to be finished. If not, pack it up and pass it on. Even that will make you feel better, and admitting that you fell out of love with a project is not a bad thing.
