I also love to do hand applique and have a number of books, the one I have found to be the most informative is "12 Ways To Applique" by Elly Seinkeiwicz. She teaches 12 different methods, includes patterns for projects and the best method to use not only for the pattern but for each element within the pattern. You won't be dissappointed with this one. I also have "Applique The Piece O'Cake Way" which is not nearly as informative, it's ok, but for a first book i highly reccomend "12 Ways..." I don't think you will be disappointed.
Have fun!!
