Adrastea is a reversible hat that buttons to create a gathered look, it is worked from the bottom up in the round. The stitch pattern works great for showing off the texture of a light colored yarn or for showing off color changes in semisolid yarns. Named for one of the moons of Jupiter, which was in turn, named for one of the nymphs that cared for Zeus in his infancy.
