Just finished this hat for me. I love how it came out. I made one for a friend's daughter using the exact pattern recently (it's from Louisa Harding's "Hats, Gloves, Scarves" book). I modified the pattern for DPN needles and added an inch to the length, so it covers my ears and doesn't have a seam, so I like it much better for me than the original pattern. The yarn is Purewool 100% merino wool.
