Hrungnir was one of the giants from Jotunheim. On one visit to Aasgard, Hrungnir drank all the ale from Thor’s cups and then while he was drunk
boasted that he was going to drink all the ale from the Aasas. Thor took insult and slayed him in a duel. Hrungnir had a heart of stone, sharp and three-sided, and even his head was of stone. But Thor defeated him with his hammer.
This scarf shows Hrungnir's triangular heart, and is knit using two contrasting skeins of fingering weight yarn. One of the skeins is an "Evolution" which means that the colour changes from one end to the other.
The pattern is charted, and includes detailed instructions on two different methods of double-knitting
