My sister is having chemo and lives in Maine where it is cold, so I made her this warm snuggly hat out of the warmest snuggliest yarn I could find, Malabrigo Merino Worsted. I used the pattern (which is more like a guideline, really) from The Knitting Man(ual).
It's a top-down hat, which I really love because they never end up too short. I've made a couple of others too, on my blog here
. And the hat above is on the blog here
, but it's pretty much the same information I just gave you.
