Waldo's Puzzle

So, do you love patterns that are a little bit of a challenge? Waldo's
Puzzle will probably fit the bill. This square is named after my paternal
grandfather. Waldo was such a puzzle aficionado, and could figure out any
manual puzzle involving rings, string, and bits of wood in a flash! The
rings in this pattern remind me of Grandpa and his puzzles.
