Hi,
Great questsion. Let's see, what is the first thing you notice about the leather? Is there a specific color? I would definitely think that a red leather coat would be all about fire. Blue is symbolic of water and brown wood. When considering the nature and essence of a cow, I would think they are very earth oriented.
In this case, what do you notice first when you encounter the leather in question?
All the best!
