Instructions for making a pentahexaflexagon
(these are also included in the download file)
First of all, fold along every crease line on the strip, back and
forth, ready for easy flexing.
Now start at diagram 1. and go through each diagram in order.
Each diagram (except 9.) has a heavy line with 2 faces marked
u and d. Fold along the heavy line, so that after
the fold the faces u and d are together, with
u facing up and d facing down onto the table.
At diagram 9., there is a triangle underneath y.
Tuck the mini strip x and y beneath this, so
you can only see x.
In the second to last diagram, stick the two faces u and
d together with glue or double sided tape.
