This is a medium bulky weight cap that is somewhere between a skull cap and a round cap in length.  It covers about half of the ears.  The pale teal, orange and purple are Corriedale wool.   The light brown is natural color llama wool that has a fuzzy texture.  The variegated medium brown is natural color Shetland wool.  The thin light teal accent stripes are a blend of Merino wool and tencel, which looks a bit like silk.  The olive green thin accent stripes are silk.  The lavender near the top is mohair.
