This hat has bobbles similar to those seen in the green hat below. It's a tighter knit though, so fits a smaller head. Probably a smallish medium. I like the art yarn top that looks sort of like a yarn garden. It's mostly wool, with mohair locks, silk and some bits of novelty fiber spun into the art yarn. The pale pink is two ply fine spun Shetland wool. The bobbles are Corriedale wool, mohair and silk.
