I took Nancy's class at Road to CA a couple of yrs. ago--she's a GREAT teacher and it's one of the best classes I've ever taken. I don't know if she sells patterns. In class, she gave each of us her basic pattern of a cat and we brought our own photos of our cat and made the appropriate changes to make it look like our own kitty. I don't do portrait quilts, either, but Nancy made this SO EASY that even I could do it!
Her method of layering the applique before sewing it to the background could also be used to layer flowers, etc.
