My brother is a runner, he has ran the San Fransisco Marathon 3 times, and when he was home at Christmas he declared that he wanted a custom hat to make the other runners jealous. He started going on and on about the expensive hats that wear for status. He specifically wanted a large hole in the top to let out steam and wanted it to cover his ears, he also wanted to make sure it would fall off when it was full of sweat (gross). I kept putting it off but since his wife went ahead and bought the yarn I felt obligated to finish it and I did, the night before he went back to California. He was pretty happy with it and excited to make the other runners jealous of his "custom made" hat.
