I used the Pressed Rib Cap & Muffler Pattern from Churchmouse Yarns & Teas. I have made this hat pattern once before for my brother who likes his hats on the slouchy side so I added extra length to it. Instead of three inches of each yarn I like to knit three and a half inches to add some extra length to make sure it covers the ears.
I used two different yarns for this hat. The variegated yarn is Manos del Uruguay Maxima in the color camo. To complement this yarn I used Astral from The Alpaca Yarn Company in Gold Rush. While I will include links to both of these yarns, please check your local yarn stores first. I always try to support my local yarn stores because I highly enjoy visiting them and being able to feel and see the yarn I am buying in person.
