O.k. I'll take a stab at it and hope I don't embarrass myself in the process. It looks like it is two seperate knitted peices knitted on two needles vs. dbl pointed, sewn/knitted together at the crown (because I see a ridge on the crown. Then I saw what looks to be a fold or tuck in the ear area.) I think creating your own pattern would be do-able. It looks like it is wider on the bottom, then decreases above the ears toward the top/crown. The area with the contrasting color could be anything you choose, even a different stitch pattern in the same color would look nice. Do a gauge swatch using the yarn/fiber you want to use. Measure the head and plan the rows and number of stitches to decrease. You have me intrigued.
