This is a finished jellyfish hat in lovely sea greens and teal blues. Fits an adult head comfortably around 20-22” head size. It does have some give so may fit a larger head. The pattern is the Twisted Jellyfish Pattern by The Twisted Hatter. From top of hat to end of tendrils is about 22-25 inches. The darker sea green has sparkles throughout and the thin ribbon has sparkles as well. Really comfortable and stunning!
