When I started, I was afraid that they might be too thin to really work as potholders, but the clever pattern leads to a double-thick cloth, and since crochet is already, by its structure, double-thick in itself, that's really a quadruple-thick cloth. (Click through the link, btw, if you're at all interested. The pattern's very simple, but it's got a nifty geometrical trick for turning a spiral into a square.)
I'm hoping to make another pair soon, so that I can have a pair out and a pair in the laundry. These work up in less than a day, so it shouldn't take too long.
Peace of Christ to you,
