That's pretty much it! Cast off when the dishcloth is more or less square. Break yarn and work in ends.
If you cast on an odd number of sts instead of an even number, every row can begin with a knit 1 (or purl 1, as you prefer). Even more mindless.
It seems silly to even type this up and put it on the site, but I think they're so pretty, and I do love textured stitches. And since I intend to give them to a dear friend (eventually), if I don't type this up now, I may never be able to recreate them (or remember what they looked like when brand new). :)
