Flexagons Inside Out
Les Pook
given in this book for constructing the flexagons. They are minimal at best. I have had this problem with origami books, too. So, I recommend a prospective buyer look at the book before buying to make sure he or she can understand the directions; what is the value of the book if you can't actually construct the flexagons and play with them?
