The snowdrift flap hat is knit top down. A single crocheted edge allows the brim to lay flat or can be used to line the hat with a soft fleece. A main color and 3 or 4 contrasting colors can be used for stripes. Some suggested stripe patterns are included as well as a link for an easy tutorial on how to line it. The sizes are for children heads 16, 17.5, or 19 inches in circumference.
