I am knitting a sweater from garnstudio.com and was wondering if there is a mistake in the pattern. I am creating ribbing on the bottom edge. The first two rows are garter stitch. Then it starts the pattern one edge stitch, k2, p3, finish with k3 and one edge stitch. When I start the second row of the ribbing I am doing the opposite of what I think I should be doing as far as knitting knit stitches and purl stitches. Where there are knit stitches, following the pattern I am supposed to be purling there. Anyone have any advice?
