I like binding the best, probably because it's that final completion. My least favorite part is sandwiching- which seems silly since I spray baste, but I usually need a little help holding the parts, and it's not always easy to find help when I need it.
I'm also not fond of cutting, especially if it's expensive fabric, I'm so worried about making a wrong cut. The house has to be totally quiet if I'm going to cut fabric from LQS. Other fabric,I'm not as worried about.
