I have too many projects on the go and too many projects that I want to start. This is my plan for attacking my projects. I updated my quilting log and was really surprised that I had more projects started that I remembered. My goal this year is to half my list of UFOs, so before I can start a new project I must finished 2 projects. Using my quilting log, I pick which UFOs I want to finish and try to work on those two projects. I pick two projects that are different and it gives me some creativity by bouncing between these two projects. I don't berate myself if I work on a third one if I really need variety but I do try to stick to my rule of finishing. Only time will tell if I can reduce the number of UFOs. I think I will always have some UFOs because I like variety but reducing the number of UFOs will reduce my stress and allow me to finish my projects quicker.
Good luck with your challenge and I hope that you will find a method that will help you.
