To use your Sketchbook Hat, simply put it on your head. It's perfect for any outdoor adventure in the fall. When choosing yarn, make sure the Lanas Light colors you pick match your preference. As for maintenance, you can hand - wash the hat in cold water with mild detergent. Gently squeeze out the water and lay it flat to dry. Avoid wringing or twisting it to keep its shape. Don't expose it to direct sunlight for too long to prevent color fading.
