I made my husband a hat to match his new coat, but it wasn't warm enough on the days when it is cold and windy. He wanted it to be a tighter knit. I decided to do a fair isle stitch to give him the added warmth of double the yarn from the yarn carried across the back. This turned out great and I am soooo proud of the way the wrong side looks. It is very uniform, I am not bragging, just happy it turned out that way.
