WMUTeach, I'm a big fan of the Piece O' Cake ladies. I learned from their book, "The New Applique Sampler." They teach the needle turn technique. There is also a way to do applique with freezer paper, and another with basting but I've not looked into those because I enjoy needle turn. Here's the link from googling 'piece o' cake applique youtube'.
