This is a slightly longer skull cap that covers about half of the ears.  It's made from bulky weight lumpy yarn on the top and medium bulky weight smooth textured yarn on the bottom.  The teal green and rust are Corriedale wool.  The red is lumpy spun bulky weight Shetland wool, and the variegated gray at the top is a lumpy spun very textured blend of Shetland and Icelandic wools.
