The Oslo Hat - Mohair Edition is a classic beanie that is worked from the bottom up in stockinette stitch using Sunday held together with Tynn Silk Mohair, both from Sandnes Garn. The first part of the hat is worked on a US 3 16" (40 cm) circular, while the top of the hat can be worked with either DPNs or a circular needle using Magic Loop. Needles are not included.
