In Knitting Nature, Gaughan blends together the natural and artistic world with 39 stunning, fun-to-knit designs for women, men, and children. Among them are a skirt patterned after the hexagonal scales nature has used to cover a domed turtle’s shell, a jacket whose collar grows in a spiral — much the same way a ram’s horn does — and a tank top with leaves that grow the same way they do on a stem.
