I originally started this hat for my mum, but I am not sure if she'll be into it. She's more a white oxford shirt lady than a funky rainbow stripe lady. I used Paton's Classic Merino (Natural Mix) and Noro Silk Garden (279). This was the first time I have used circular needles successfully, I just used a 16 in. no. 7 as God intended. I figured I'd give it a go before I tried magic loop or 2 circs. I loved it, but I wasn't too thrilled when I had to switch back to DPNs because I realized my no. 7's were otherwise occupied in a beret I am knitting, so I finished up the crown on no. 6's.
