This cowl is a great way to practice some colourwork. There is both a chart and written instructions.
It is knit in the round seamlessly from one edge to the other. After casting on you will knit the ribbed edge in 2x1 rib (k, k, p) and then follow the chart or written instructions to repeat the pattern. The yarn chosen changes colour gradually to highlight the cactus pattern.
