I'm no help either. I LOVE LOVE LOVE my ipad, but after purchasing one quilting book for it, I realized that in this case, hard copy is better. Not only are the diagrams too small, but the book I purchased from amazon was formatted for the Kindle so it was B&W instead of color. You couldn't make out half the samples (although it was a good exercise on why color value is so important). I wound up having to rebuy a paper version.
