I don't have these books, but I went to Amazon as usual to check out the reviews. That's what I would advise you to do. The very first review on the Encore book says that if you only buy one of the books, buy the Encore one. Apparently it has all the info of the first book plus additional info, and patterns that are more exciting. On Amazon the first book has 37 reviews, Encore has 9 reviews, and Encore has a "look inside" feature. I always go to Amazon to check out reviews and look inside, if the book has that option.
