I can't say there is a part of quilting I like least---I have something I like about every part of it. I never allow unwashed fabric into my sewing room! The moment it comes in the house, it's in the washer. That way, I never have to wonder if I have washed a certain fabric when I am getting ready to sew. I used to dislike handfinishing my bindings---I piece and quilt on my machines---but recently I find I enjoy the task of handwork on the bindings.
