Over the years I have made a few cows knee's and used other make shift alternatives for keeping my locks dry. I almost always lose them so now I am in need of another one. I have a good sized chunk of brain tanned deer hide that I plan on using but was wondering how everyone else goes about making one. Also do you water proof the seams, the whole thing or what and what do you use to do so? The deer hide I have has been smoked and is very supple.
