Let the mathematical fun begin…

Gobolink Symmetry

I admit, it doesn’t really have anything to do with math, but it looks like a fun way to spend a snowy afternoon:

According to the authors:

Jet black ink should be used, and a good quality of unglazed paper. The ink should not be too thin. The table should be protected from accident with several thicknesses of newspaper. . .

For a specially invited Gobolink party the company may dress in any grotesque fashion, remembering only that both sides of their costume shall be the same, this being a feature peculiar to Gobolink attire.

I got tricky with the hidden present this time. The outside of the envelope changed insignificantly. It read:

That you cannot see…

But the real departure from normal came with the poetry inside. The poem was a success, in that he laughed at all the appropriate spots, but the hiding place turned out to be a little too good. Can you find the two clues in all this mess?
