I found this online. Full disclosure, I did NOT read it or watch the video clips. I just scanned over it.

Imdid not know about using bull frog leather.  I currently use kangaroo leather.  

And people wonder why their bows bounce. I think they are jumping with all the bullfrog and kangaroo leather.

@Irv Just the thought of it being snake skin gives me the willies! Would never buy a snake a snake skin one. 

My son literally invited a garden snake into our house when he was little. He was proud, I was petrified! He opened the front door to come inside and said, “Look, Mom, a snake!” And he held the door open for it! I said, “Close the door!” Too late. We had a raised ranch at the time and it slithered downstairs. No cell phones then. Had to lose track of it and go to the wall phone. You know who got a call at work!

Spent all night looking for it because we were heading out on a road trip in the morning. For some reason, my husband lifted the washing machine up and found it on the lip of the front metal part that was curled in at the bottom to the inside to make a smooth outside. The snake was on the lip. It sure looked bigged when my son invited it in.

Got hit in the face with a garden rake due to a snake, too! It was resting on a rock, so had a folcrum to make it flip up is stepped on. I saw a snake and ran and stepped on the rake just right and the handle hit me right in the face! That was bad enough, but my son, much older by that time, was driving by with my father-in-law as it happened. After he was finished helping his grandfather and came home, first thing out of his mouth, “Hey, Mom, did you see a snake earlier today?” So, no snake skin on my bows. No broken nose or black eyes from the rake, but a really sore left cheek.
