I crocheted a hat using spring/summer yarn. ^^ I've crocheted it with a combination of silk and cotton yarn, along with a hand-knitting yarn made from Japanese paper, using two strands together. Size: Inner diameter approximately 52 cm Color: Blue - I've combined navy blue and blue yarn. The brim has a curled look. It turned out a bit small for adults, so I hope it will be used by children or those who prefer a smaller fit. * It will be shipped folded flat. * Please understand that this is a handmade item. Thank you.
