Picture shown is the small size knitted up and lined on a 4 year old boy. This hat is available in three sizes, small medium and large. Small is 9 1/2” diameter. Medium is 11” diameter and Large is 12” diameter. The edge of the hat, along the face line is crocheted for a more finished look. I do recommend lining these hats, it just makes for a better fit and it will block any moisture or cold from getting through. Instructions for how to line your hat are also included within the pattern. This is now a Sheep Shop Yarn Co. pattern and can be purchased from any retailer who carries their products.
