Bóithrín striped beanie - knitting pattern

Bóithrín (pronounced ‘Boreen’) is Irish for ‘a little road’.

My little boy loves cars. And trucks. And bikes. And aeroplanes. And motorbikes. And lorries. And diggers. And cranes. And trains. And buses, which is pretty handy, as we live in a bus. It doesn’t matter whether it’s an old rusty banger or slick stickered racing car, if it moves and makes a noise, he wants one.

And so this Hat, inspired by race tracks, road markings and tyre treads came to be. Bóithrín is the perfect Hat for little boys obsessed with vehicles, a modern take on the classic intarsia motif pieces and the perfect project to practice a few new techniques.
