More and more clothes seem to be coming with those little symbols on the care labels instead of English instructions. At first I resisted, but then I took the time to learn what they meant and now I'm a fan. They take up less space, are quicker to read, and are international. The linked site even has a handy PDF that you can print out and hang up in your laundry area.
Some of the older symbols have temperatures inside the symbols, but I like the new ones, which use one, two, or three dots. The temperature was always in Celsius which required mental arithmetic and the digits were often hard to read.
