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 instarsia motif pieces, and the perfect project to practice a few new techniques.
