I had an idea.  So I made a bow for my son.  Its only 36" long and made out of Osage.  Wife is worried it will break kids being kids and all.  I mean at 8lbs at 12", the limbs are very thin.  So I thought about sinewing them, but that addes draw wieght.  So thought about thin rawhide, but most of it is not thin enough for a bow this small.  
So I thought about tanned snake skin.  I was going to rattlesnake skin the bow anyway for it be cool for a kid.  And just like dads, but isn't tanned skin kinda tough?  Wouldn't it give a little protection against exploding for a kid?  Maybe kill two birds with one stone so to speak.
