This is a medium to bulky weight loose knit hat that fits most sizes, fully covering the ears.  The blue is Corriedale wool.  The middle lumpy section is a blend of wool, mohair, silk with bits of novelty fiber and some gold/green sparkly angelina.  The other two lumpy sections are four ply fine spun wool/silk blend with small rosettes worked into the yarn.  This is a tricky maneuver for sure, and was done by one of my favorite online spinners at Joybilee Farms in Canada
