Here's a close up of the stitch pattern:
It's called Dot Stitch and I don't know if I've ever come across any patterns that use it. I don't know why not - it's lovely to look at, doesn't bias, doesn't roll, and is so much less tedious than most textured patterns. I love seed stitch and moss stitch but can't really say that I love knitting either of them. This textured stitch is only patterned on the wrong side, the right side is simply knit.
