This is a medium bulky weight hat made from Corriedale, Merino and Shetland wool with tussah silk accents.  The black ties and pompom are Merino wool.  The pompom is purposely made with different lengths of yarn to give it a more interesting look.  The greens and thin light gray stripes are all Corriedale wool.  The thin very dark green stripes that look gray are Shetland wool.  The bright green design work and thin stripe near the edge of the main body of the hat, as well as the thin olive stripe near the top are all tussah silk.
