Okay, my pregnant brain seems incapable of basic math. I want to do a waffle weave blanket in a chunky yarn, casting on about 60 stitches. I'd like to do the edging in garter or seed stitch with alternating blocks of garter and stockinette in the middle. But my brain will not allow me to figure out the proper pattern. You know: k6, p6 across the row, etc, do that for six rows, switch. But the edging is screwing me up, and I can't figure it out. Help!
