I don't do this yet but this was my first reaction to seeing this page. The originals are a bit cryptic when you don't know them, but simple and easy to memorize and even easier to match against a printed sheet next to your washing machine. I will go and make one sheet for me now. In fact, this is the stuff that should be part of a high-school curriculum!
