The Elf Hat is hand-knit of 100% acrylic yarn, washable and totally non-allergenic.   In the Harry Potter books, Dobby the house-elf collects the hats that Hermione made to free the Hogwarts elves, and puts them one on top of another, since he knows the other elves do not want to be free. So these hats look like a pile of hats, five in all, with different colors and patterns for each.

This hat is a large adult size.
