Are the flour sack towels regular towel length? I'm not sure I've seen these at stores. But then again, it's not like I've ever been looking for them. I did see them for sale through Dharma Trading, but I think they're sold in pack of 10 or 12. Several sizes, too. I'm so bad at guesstimating measurements! (they also have cheap silk pillowcases in case your'e looking).
