I have had 5 UFOs in a closet for about 5 years that I really didn't like and didn't want to finish. I took one out just before Christmas last year and made myself quilt it. It's really cute and I will give it to the granddaughter sometime in the future. I just took the second one out last month and finished it. It is really pretty and my son is going to love it. I will eventually finish numbers 3 and 4 but I think 5 is destined to be re-homed without being finished.
I wouldn't put the side borders on, just stitch around the edges to prevent stretching. Toss in a closet. Take it out in later this year and if you still don't like it do a quick stitch in the ditch and give to someone who would love a Christmas gift.
Sometimes your mind set changes and you go back and finish what you started. I also give the UFOs a chance to change my mind
