To use this hat and socks set, simply put the hat on your little one's head and the socks on their feet. They are stretchy, so they should fit easily. When it comes to maintenance, you can hand - wash them in cool water with a mild detergent. Gently squeeze out the water and lay them flat to dry. Avoid wringing or twisting the items, as this can damage the yarn. And remember, keep them away from sharp objects to prevent snags.
