Wow, I learned something from your comment! I always thought onyx was black. I had to google it after I read your comment. You're right... it does look like the amber/orange colored onyx. cool... thanks for the observation.
haha! A little bit of hair goes a long way! When I started wanting to try to work with horsehair it was an interesting adventure to try to find some. Then my mother-in-law found out I was looking for it. She has a friend with horses. Turns out the friend was just about to groom her horses and was frustrated that her dogs had been nipping at the horses' tails and making them ragged. So she cut off two entire tails worth of hair and gave them to me. I should have enough horse hair to last me several years!
