Materials:
yarn in grey, cream, red and a black

Use instructions below for beanie OR follow this other link for a flatter beanie top.
Start with cream color by ch 4, join to first ch to form ring (or use magic ring).
1.ch2 6dc in ring. Join to top of ch 2 (UPDATE: OMIT THIS ROUND, THIS SEEMS TO MAKE THE HAT TOO POINTY. START INSTEAD ON ROW 2 WITH 12 sc FOR THE FIRST ROUND AFTER THE MAGIC RING. NOTE THAT CH2 COUNTS AS FIRST SC.)
2.ch2 2dc in each dc (12 st) join every round unless otherwise noted
3.ch 2 (2dc in next dc, dc in next dc) 6 times (18 sts)

3. change to cream yarn. sc all the way around twice, doing two sc in each of the "corner" stitches. Leave a long tail for sewing to hat.
Eye (make 2):
Use medium thickness black yarn using 6mm crochet hook. Magic circle. Chain 1, work 6 single crochet. Join with the beginning stitch. Cut off a long length of tail for attaching to face. Align and sew the eyes to the face. Sew in X's at the center of the eyes.
Crocheted Flower Pattern (link)
Using a size H hook, chain 4. Join the end to the first chain with a slip stitch to form a ring.
R1: (single crochet in the ring, chain 3) 6 times. Again, join the last stitch to the first single crochet with a slip stitch.
R2: (single crochet, chain 1, 3 double crochets, chain 1, single crochet) in each space created by the chain 3.
R3: Now you begin working in the back of the flower you have started creating. (single crochet around the first spoke, then chain 4) 6 times. Join last stitch to first stitch with a slip stitch.
R4: (single crochet, chain 1, 5 double crochets, chain 1, single crochet) in each space created by the chain 4.
R5: Repeat round 3, but chain 5 instead of 4. Join last stitch to first with a slip stitch and weave in ends.
If you want to add another layer of petals, repeat Round 3, increasing the number of stitches in the chain by one, and Round 4, increasing the double crochets by two.
Earflap braided tails:
I used four strands of each color to attach tie strings on to the earflaps and braided them, then trimmed the ends.
