Light blue knit hat from Everwood

My hubby and I have been binge-watching Everwood and there was a hat worn by Anne Heche that I would just love to knit, but I have no idea if there is a pattern out there for it or not. I took a picture of the tv screen for reference. I’m not all that good at making my own patterns, but I’m sure there are more knowledgeable people here who might be able to help. It looks like a picott edging, then possibly the next section is knit and sewn on, then the top is cable diamonds with bobbles. Anyone have an idea?
