This is a simple stitch textured cowl/hood (you decide the length). Suitable for beginning knitters. Purl ridges make the cowl easy to scrunchy down or pull up. You can wear the ribbed end on top if you are wearing it as a cowl to make it snuggie around your neck or, wear the purl ridges on top if you are pulling it up as a hood.
You can use any worsted weight yarn, I also think handspun would knit up well, especially for the cowl version. Good for yarn that would show texture.
