This pattern is one I found last March. Its a free pattern from Lion Brand wool, pattern # 70464A. Im only copying it here because the link in my old email keeps going wonky.
It was originally meant to be made with a double strand of wool and a size P hook.
I made it with a single strand of worsted and a size H. And it turned out fine...
