After 5 winters in New York State I have to accept the fact that my cheap hats or really old acrylic hats just aren't going to cut it. So I made a double sided Tychus(from Knitty).
I knit two Tychus hats. One with Joker wool black and Lion Brand Wool White and the second one with Moda-dea wool and silk green and Lion Brand Wool White. Needles were size 4.5mm. I love the feel of it, granted I finished it about a month ago and the cold weather is gone now, but I will be prepared for next winter.
