My son is a rabid red sox fan, and while it is a stretch to call him a boy, he is my boy! I started this last year and finished it last night. He should have it - the weather here is frightful - but it will be early next week before he sees it. The pattern is “Man Hat” by Ashley Haven, available on Ravelry.
I love the way this is so cozy and can be turned up if a little oversized or gets stretchy. For years, he had a red sox hat, but that went missing. I made two for his father, similar, but in blue. Can't wait to see him in it!
