This week's problem was more of a puzzle than a problem, with a
surprising yet simple solution (simple once you knew the answer!).
We received correct solutions from

Step 1: Number on both sides of the paper.
Step 2: Fold in half the long way so that you can see the stamps
according to the figure below.

Step 3: Form a loop by moving the end with the 7 around the back and
insert in the pocket on the left behind the 1 and in front of the 4.
Step 4: Slide the stamps in until the 7 is on top of the 8.
