This hat is made from several different bulky weight wools and fully covers the ears with the brim turned either up or down.  The brim and variegated ocher/olive stripes are Corriedale wool.  The teal green is uncarded, more textured Suffolk wool.  The dark olive green is gray Jacob wool over dyed with green.  The dark brown stripes and circle at the top are undyed dark brown Romney wool, and the gray stripes are natural undyed gray Merino wool.
