I love the video from Pacific Rim. It was very helpful learning and being able to go back to watch when I needed refresher. The dragonfly wall hanging comes with the video so you won't have to buy a pattern too, unless you want to :-)
I don't think there is any one "right" or "wrong" way to applique if you are happy with your work I don't think it matter is if its pre-quilted or not.
Happy Stitching :-)
