Designer notes:

Description:

Twilly is a DK-weight beanie featuring an easy slip-stitch brim. The brim is lined with 1x1 ribbing that is knitted as you go and joined seamlessly. This double layer provides extra warmth and a soft, stretchy brim edge.

The rest of the hat is worked in stockinette stitch, with subtle crown decreases for a clean finish.

Instructions are provided for three sizes -- youth, adult small and adult large. The height of the hat can easily be customized if you prefer a slouchy or more fitted shape.
