This is the fourth of five posts in a series on sewing ribbing.
Jump to half-stitch seaming in 1×1 ribbing, full-stitch seaming in 1×1 ribbing, or full-stitch seaming in 2×2 ribbing. (In this series, “half-stitch seam” means any seam consuming half a stitch from each edge, and “full-stitch seam” means any seam consuming a full stitch from each edge. See the first post for more information.)
