This beanie was knitted with a blend of both acrylic and wool. It fits most adult heads. This can be machine washed but hand wash will extend the life of your hat.
My yarn and inventory are kept away from my pets. I do have a dog and rabbits, if you have allergies I suggest washing this before wearing. All of my creations are completed with a hand sewn satin tag (soft not itchy) with washing directions and my yarn rabbit logo.
