"First turn the paper over so that the number 1 is face-down on the lower-left. Then fold the right half of the paper onto the left half so that the back of the 6 is against the back of the 1. Then fold the lower half of the paper onto the upper half so that the front of the 6 is against the front of the 7.
Now it gets tricky. Clasp the inner 6 and 7, then fold them up together so that the back of the 6 is against the back of the 5. (This actually tucks the 6 and 7 behind the 8) Now clasp the outer 1 and 2, then fold them back together so that the front of the 2 is against the front of the 3. And, finally, turn the whole thing over. The number 1 will be face-up on top, followed by the rest of the numbers in consecutive order."
