Personally, I have one in the frames being quilted, one on the design wall and one sort of bouncing around in my head. I would go bonkers with a bunch of started and unfinished stuff. With that said, I hear often of people finding quilt tops in the belongings of those that have passed. Perhaps, those that don't finish their projects are like the ones that did the quilt tops, but did not actually quilt them. You may enjoy the planning and design, and even perhaps piecing the top, but the actual quilting is a chore to you, so you put it aside and go on the the nest quilt planning, design and piecing. That's OK. If you go to the great beyond and leave some tops that still need to be quilted, I'm sure there will be someone who will appreciate what you did do and be most happy to finish the quilt themselves.
