That's exciting! Thelma found another Llama hat, that differs quite a bit from the others. This time the hat was pictured in Bolivia instead of Peru. As you can see the ears are placed more to the back of the hat. The leaves of the palm tree don't grow from the stem. And it seems only the first few rows (recognizable by the yo holes) are knit in chevron sts.
Certainly worth wile to write down a pattern for!
The pictures were taken by Linda de Volder (a.k.a. Peregrin@ on Flickr). She took them at Santa Cruz in Bolivia, at october 13, 2004.
