Yes - finished is better than perfect. Who are these tops for? They're waiting. Oh, you are just going to donate them? Still waiting.
I would start with the simplest patchwork designs and straight line walking foot wiggly line and diagonal crosshatch.designs. You can knock out at least a 3rd of them.
set up a basting station in front of the TV and put on the entire Lord of the rings. (I use my 6' folding table). Heck - how many avengers movies are there now? Rather binge watch Brigerton or all 25 seasons of This Old House? You pick!
Basting and quilting the big guys might be worth working with a longarmer for. I think you can quilt and base anything yourself up to about a twin size. After that it really does start to get challenging on DSM. But if you finish the smallest with the above 2 tips (TV basting and straight line quilting) you will truly realize the potential of the quilt.
PS. Also fabric degrades over time- even if put away out of direct sunlight. Critters can get in and make nests also. Best move all those quilt tops along.
