The most
Hmmmm
Well before the days of drastically fixed income I used to like picking out the fabric best. I can't afford to add to my stash, only buy for specific quilts (my stash is adequate, but I'm going to have to add some lights--oh boy trip to LQSs), so now I have to say that piecing is my favorite part.
I love to sew on the machine and I love to put puzzles together.
