Hat ARNA is knitted with needle size 8/US 11 and worked in five colors of Schachenmayr Boston. This could be your first Fair Isle project if you haven´t had the courage to attempt this technique. ARNA is knitted bottom-up in 26 rounds – you can do it! Any by the time you are working on the second hat, it will seem like you have always been knitting with two colors. Just try it!
