Not so much a building technique, just what have you seen type of question...
I am wondering how far around guys can get away with wrapping a snakeskin? Take an old bear recurve for instance. It has a totally flat back to it. So it is very obvious that if you back it with snakeskin, the snakeskin would stop at the edge of the flat back of the limb. Like this:
But picture a longbow or selfbow with more of a round sweeping profile where there isn't such a demarcation line between the back of the limb and the side of the limb like this:
How far towards the belly can you take the snakeskin?
