The pdf should be printed, in color, double-sided (flip on short edge).
Make sure you choose "Actual size" (NOT "Fit" or "Fit to Page").
If the puzzle is printed correctly, the magenta lines on
the front and back should match up exactly.
If they are not exact, the puzzle is still solvable,
but be aware that there is inaccuracy/slop.
Z-fold along the magenta lines so that
"Welcome To Penny Park" is on the front, and "Come visit us at the castle!"
is on the back.
(The professionally-made brochures handed out at hunt didn't have
the magenta lines.)
