From the pattern description: Funky, chunky, and quick to knit, these legwarmers are worked in an irregular brioche rib texture that is achieved by knitting into the stitch one row below. The cast-on and cast-off edges are knitted in a contrasting colour, although the legwarmers can be completed in a single colour if preferred.
