This knit cap was lovingly and painstakingly knitted for me by my wonderful wife. She adapted the pattern from a similar hat showcased by Matt Parker.
In an fascinating presentation at the Royal Institute, Matt Parker claimed to have the nerdiest hat in the world.
First, if you haven’t done so, I encourage you to watch the entire presentation. It’s educational, entertaining, and simply amazing!
After hearing Matt discuss his custom hat, I approached my wife with an absurd idea. I wanted a custom version of the “nerdiest hat in the world”…that was…(wait for it)…even nerdier. With a bit of convincing she graciously agreed (Looking back I don’t think she realized the madness she had agreed to). After what seemed like endless counting, lots of measuring, a ton of frogging, and some artistic magic, the hat was finally ready.
I now surmise that THIS is the nerdiest hat in existence.
