I was playing around with yarn one day, looking for a way to make a raised ridge texture that was more interesting than the Ridge Stitch (single crochet in the back loop only). And then I found it -- A stitch that looks like you've sewn a braided cord right on the front of your stitches!
I call it, unsurprisingly, the Cord Stitch.
The Cord Stitch is a 2-row repeat, in which the first row creates the cord effect, and the second row emphasizes it.
