Approximately 40 species of dolphins inhabit all types of aquatic environments, from fresh water to oceans. In the waters of the Pacific Northwest we have the J-Pod. This hat was designed to honor this magnificent mammal. The pattern includes 5 hat sizes, from 3-10 Child to XL Adult. The worsted weight hat is a simple single brim worsted weight watch cap knit on a circular needle, plus double pointed needles for the decreases on top. (I use the Magic Loop for the entire hat.) The dolphin pod encircling the hat are embroidered after the hat is complete. This pattern assumes knowledge of duplicate stitch, also called knit embroidery or Swiss darning.
