I am 31 years old and just learned the damp paper towel under the cutting board trick
My cutting board has slid around my counter for basically my entire adult life. Every time I chopped something I would do this dumb thing where I tried to hold the board still with one hand while cutting with the other. Someone watched me doing it last weekend and asked why I did not put a damp paper towel underneath it. I thought there was no way that would actually help much. It does. The board does not move at all. Took about ten seconds and fixed something I have been annoyed by for years. Posting this for anyone else who has been fighting their cutting board every night for absolutely no reason.
