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.

Wonderful car ride, plane, etc. distractions. https://www.amazon.com/Scientific-American-Mathematical-Puzzles-Diversions/dp/B000K0K4J2 https://www.amazon.com/Scientific-American-Mathematical-Puzz...
