This is a standard length skull cap designed to come down over just the top of the ears or be worn tucked behind on an adult.  It would also be fine for a child, in which case it would probably cover most or all of the ears.  The brighter ochre near the top and the yellow at the very top are organic cotton.  The wider section of slightly darker ochre is linen, as are the thin green and light tan stripes.  The beige stripes around the top and edge are undyed colorganic cotton.
