How to make a TRIFLEXAGON

If you've seen Kjartan (the author) talking about the Murderous Maths books, he probably demonstrated some of his different FLEXAGONS.
A flexagon looks like a piece of folded card which you can turn inside out. The good bit is that you're never quite sure what you'll see next.
