The idea for the top! With double vision, reading is somewhat difficult, so I sometimes mis-read numbers in patterns. (What that really means is that I don't follow instructions well!) I wound up 'inventing' a few quilts because of that, and discovered I liked to do that. It is so cool when I'm rummaging through my stash for a fabric for one quilt only to become inspired by finding a completely forgotten fabric that, for some reason, flashes a quilt top into my head. More than one quilt has been, uh, delayed because of those flashes of inspiration!
Next is the follow through - cutting, piecing, etc. The part I truly dislike doing is binding. Ugh.
