Hi! I was looking for a pattern somewhere, anywhere for this as well as I have a friend who just asked me to make one for her (and after seeing it, I really want one myself >.>). At one point, many many moons ago, she responded to a comment on her Deviantart account in regards to a pattern! So, I have the hood/scarf pattern.....but she keeps the ears a secret ^.^ but I'm sure it wouldn't be too hard to find a pattern and whip up some ears! Anyways! Here is the pattern that I found:
"I only sell locally. I wrote up a simple pattern for it.
51 stitches on 15.0 mm needles, first 5 rows k3 p3, then alternating knitting a row and purling a row, so you have 30 rows all together and the cast off is where you corset it together, then knit 2 mini-scarfs 5 stitches 30 rows down but near the end you k2tog k1 k2tog then k3tog and tie off for the tapered end. weave the non-tapered end onto the bottom side of the brim and your done!"
