Cut out the trihexaflexagon template and fold along the centre line.
Glue the insides of the folded paper together to reveal a strip of paper with images on the front and back.
Start folding the strip along the line of triangles. Begin on the side with words GLUE printed either end. FOLD the triangle with GLUE written on it IN towards the next triangle. If you have folded it correctly, you will no longer be able to see the word GLUE.
