There's another person who makes bow ties from all sorts of things such as Legos, sheet music, comic books, dictionaries, chalkboards, and vinyl records. Questlove can be seen wearing these ties sometimes on The Tonight Show. I bring this up however, because they also make ties from Scrabble tiles. The cool thing they do is spell out whatever word you want on the tie with the tiles.
In any case, I love that Concentration tie. I don't know what other board games you have that would make great ties, but I can't wait to see.
