A Hexaflexagon is a paper toy, a little bit similar to the well-known "heaven and hell", only more subtle!
In the applet on this page, you can click 3 patterns to select which should appear on the Hexaflexagon, and then
create a template for a printout by pressing the cut off button.
The instructions below explain how to build the Hexaflexagon out of the craft sheet.

You need scissors and glue and the printed the craft sheet.
Step 1: Print and cut out.
Step 2: Fold in the middle and glue both sides together.
The glued strip looks like this:
Step 3: Now fold along the triangle edges in both directions (these will become hinges later).
The strip now has a lot of kinks. Then unfold again.
Step 4: Now fold the strip in the middle once as shown.
Step 5: Turn around and fold down the lower two triangles at the point shown here. Then turn again. After turning, you get the picture below (right).
Step 6: Now fold up the lower two triangles. Before doing so, cover the white surface with glue and paste it to the other white surface when folding it over.
Step 7: That’s it! Finished!
And what can you do with it now? Check out the film here. You can move all the surfaces to the front by flexing them.
