   This book has some nice cuttable flexagon templates on thicker paper, with designs: https://www.amazon.com/Fantastic-Flexagons-Hexaflexagons-Oth...

   The designs are fun, although I find that the thicker paper actually makes them a bit harder to fold and flex than typical printer paper.

   If you find flexagons interesting, you might like trying to find a copy of Martin Gardner's "Scientific American Book of Mathematical Puzzles and Diversions" at your local used book sale. The first chapter is about flexagons and it gets better from there! Wonderful car ride, plane, etc. distractions.

   Martin Gardner's Mathematical Puzzles and Diversions et al. I devoured them as a boy and made me want to be a mathematician, at which I failed. That failure turned into a 43 year career of puzzles with computers. Even now every day has a puzzle to be solved.

   My dad had two of Gardner's books. I loved puzzling over them as a kid - enough that I bought my own copies for my kids to discover. I credit those books with much of my interest in logic.

   Gardner's puzzles always had a beautiful simplicity to them. The solutions are sometimes fiendishly hard, but the problem is always accessible to the layman - no great grasp of mathematics is needed, just the ability to think logically and rigorously.

   Steinhaus, Mathematical Snapshots Polya, Mathematics and Plausible Reasoning Pappas, The Joy of Mathematics Gardner, The Colossal Book of Short Puzzles and Problems Winkler, Mathematical Puzzles: A Connoisseur's Collection Andrews, Number Theory (Dover Books on Advanced Mathematics)

   - The last book is not really that advanced, It can be understood by most with an understanding through high school algebra II.
