Cute for boys and girls alike. With all the little ones loving dinosaurs now, this would make a very appropriate gift! We used a bright green, but you can choose any color that you think the child would love for a dino-mite hat! Easy to knit pattern using worsted weight yarn, 16-inch circular needle, US # 8. Make one for all the kids this year, as this is very, very easy to knit up in no time at all!
