This is a one size fits all hat designed to fully cover the ears.  The bottom edge is extra bulky weight Corriedale wool.  The lumpy section just above that is a blend of wool, mohair, silk & blue sparkly angelina. plied with red cotton cord.  The sparkly does not show up well on computer so can't be seen well.  The purple/olive lumpy section above that is thick and thin spun bulky hand painted wool plied with dark burgundy thin spun wool.  The solid color red, blue and teal are all Corriedale wool.  The lumpy section near the top is more of the hand dyed bulky wool plied with red cotton cord.
