From the magazine:

Catch the spirit of sand and surf with this easy summer soy knit. Cotton is the usual choice for hand-knitted skirts. It is a mainstay of summer knitting, yet it can often be heavy, lack drape, and loosen with wear. The beauty of soy yarn is that it looks like light cotton, with the drape and airiness of soy fibre, often referred to as vegan cashmere. You’ll love the way this skirt feels and wears.
