I went to a lecture by Joyce Hughes. Her work is exquisite. I bought the new book she has out and it does look like it may be a good way to introduce yourself to the technique. (I'm a sucker for quilting books and panels). I haven't cracked it open yet at home, but since you mentioned it I'll study it this week and give you my opinion. Can't think of any videos I've see on this topic offhand but someone else may have an idea.
