This past year I determined to get all my UFO's completed. I have finished three of them so far!! I'm happy about that. One top was finished three years ago!! Now it's quilted!! I have a wallhanging coming up soon to finish. It's been pieced for four years! I just took a break from my UFO's to make a few bags - they will be Christmas presents. Today, I go back to UFO's by finishing piecing my daughter's baby blanket (for our first grandchild!!) I started piecing it two years ago - before she was even married!! :)
No reason you shouldn't take a break from one project from time to time!! It makes it easier to finish up that last lap when you DO get back to it
Sorry to hear about your mom.
