For your purpose yes, it works obviously but indeed, armors and things that needs to be tough yet flex a bit boiling wouldnt work, or at least not as good. I am actually looking into making an armor if boiled leather, do you have any indication how much shrinkage in % you get when making something? Seeing leather isn't all that cheap I want to make sure to buy enough and not end up short on leather and forced to use a whole different piece.

Boiling is actually not quite the right term for it, as far as I can find and know the temperature is around 30-40 degrees celcius for water or maybe a bit hotter and less time submerging the leather but not scalding hot water. This will ruin your leather as Lederrudi found out. Also possible to use wax to harden leather or even after using water to even further stiffen the leather. http://www.lederhaus.de/ is a europe based shop with a bit of info about it as well. you can choose the language in the front page menu to english dutch or german, even chinese.
