Fellow geeks and crocheters, I was tasked with making my father a hat that was suitable for wearing in public. After last year's "unwearable" viking helm with horns, and the year before gifting him a blue Santa Hat with Spock ears I think he missed being able to wear my gifts the other 363 days of the year he's not Christmas-ing.
I have succeeded and made a (booorrrring) plain navy "watch cap" but that wasn't enough (to prevent you from nodding off, I have neglected to include pictures). So I made this attempt at subtle geekdom. I'm just concerned it's either too subtle or completely indiscernible.
