UPDATE: It's National Ugly Christmas Sweater Day, so we had to bring back this wonder of knit and tears Bryan specially prepared for us. - SG
Like many trips down the internet rabbit hole, this all started with a desire to own something I saw on TV, namely a sweater like the ones worn back in the day by board track racers. Before asphalt had been perfected, or engineers had figured how to pour concrete at the type of angle needed for banked ovals, motorcycles raced of giant ovals of wooden boards. For safety gear they had leather helmets and wool sweaters, which did not keep them safe but did make them quite stylish.
What follows here are some of the other things I found while looking for that board track sweater, as well as where to get one of those.
