This is a relaxed-fit bucket hat knitted with soft, calm indigo yarn. The overall color is subdued, but the white trim and patterned knit provide an accent. With a comfortable feel and warmth perfect for spring and autumn, it's great for going out. As this is handmade, we appreciate your understanding. I made this with reference to the video by Itsunomanika 62-sai.
