there's not much I dislike about quilting--- probably not having enough room in my studio would be top of my list.
I get bored with piecing if it involves doing the same thing over and over, and I don't enjoy following patterns as much as I enjoy designing my own, or just diving in and working without anything pre-planned (which I think is lots of fun) but basically, I enjoy petting my fabric, designing, shopping my stash, using my scraps, making crumb fabric, sandwiching and quilting. Oh, ironing is not my favorite thing...
and I really, really love finishing up a UFO
