Here’s another fact about rugs, and then I’ll get back to the story. They are graded by how many knots they have crammed in every square centimeter. So if it only has sixty knots in one centimeter of carpet, then you’d see that rug on the floor of a tea house in the bazaar, and you’d be welcome to step on it. But some rugs have 400 knots in one centimeter, and if you owned one as small as a pillowcase, you’d still be rich.
