3 hour class: Corrugated Rib

Take the next step in stranded colourwork. Corrugated ribbing, as seen on the edges (cuffs, collars and bottoms) of many traditional Shetland garments and contemporary knits, involves changing between knit and purl stitches. It is a beautiful way to add coloured vertical stripes to the existing vertical stripes of your ribbing.
The addition of a second colour to ribbing removes the reversibility of a standard rib (due to the floats) which can, counterintuitively for a rib, easily cause the edges to roll. This leaves the knitter with plenty to consider! This class will add to (or begin) your knowledge of corrugated ribbing and help you avoid the pitfalls of it, allowing you to add this visually striking technique to your knitting arsenal with confidence.
Anna is a huge fan of this approach to ribbing and you will find it in an ever-growing number of her patterns, such as the Sólja Sweater, Signal Hat and Visser Sweater.
