Robert Sabuda's Christmas books are incredible. But it's not hard to make simpler pop-up cards and books yourself. I've been teaching the subject for 25 years, and have two books out on the subject: "The Pocket Paper Engineer, How to Make Pop-Ups step-by-step" if you're interested in trying some on your own. I've taught kids, parents, teachers, and seniors, and they all love it. Carol Barton
