These acorn hats are perfect for autumn. I made them using Yuzawaya's "Soft Wool Yarn." The soft, gentle yarn is not itchy and goes well with natural-style clothing. The color is "greige," with a hint of brown. I made one in the same color for my 3-year-old daughter (head circumference 50cm), and I've included a photo of her trying it on. This one is almost the same shape. Please consider getting one for your autumn walks (o^^o)
