This hat is made from medium bulky weight yarns with fine spun accent stripes.  It's slightly longer than most of my longer round caps and should fully cover the ears.  The wide greenish ochre wide stripe is Corriedale wool.  The slightly darker wide stripe in the same shade  nearer the top is Suffolk wool, and has a more nubbly texture.  The flower is tussah silk.  The pale blue and gold accent stripes are also tussah silk.  The dark teal stripe that intersects the middle of the flower is Merino wool, and the gray just below it is kid mohair.  There are also a couple of hard to see thin teal stripes that are llama wool.
