 Thus, flat knitting involves knitting each row on the right side, then purling each row on the wrong side, etc.If each row is knit (no purls) this creates garter stitch, which has the same appearance on both sides and creates horizontal ridges offset by valleys, rather than a knit and purl side.Patterned stitching, such as cables, can be accomplished with either flat knitting, or in the round, however the technique must follow the desired pattern.
