Each hat is a one-of-a-kind work of art, combining color and texture to help you make your own unique fashion statement. I do not use a pattern, but let the yarns guide me as to size and shape. From 2-4 yarns are used at a time to create interest. Vintage buttons and trimmings from my decades of collecting (while a costume designer) make sure each hat is a stand-out. Diameter of top of hat when lying flat is 10 inches. The opening of this hat will fit from 19" to 23".
