Psychadelic Sundaze uses Knit Picks Galerie yarn in the Psychedelic colorway. It is knit from the bottom up in a simple rib and garter stitch pattern. The intention here was to let the beauty of the yarn shine through without a complex stitch pattern to overwhelm it.
Galerie yarn comes in lots of fun colors. I was hard pressed to choose just one to work with. The style of the yarn reminds me of Noro yarns. It has a rough hand with amazing color. Worked tightly, the hat does definitely keep my ears warm. I wore it on some pretty cold days in NYC and my ears survived.
