What is the probability after relaxing an alum tanned lifesize caribou skin from 1992 will hold up. I have contacted Ben Zuke of Modern Fur Dressing. He explains the skin sitting for that length of time will have acid rot and may destroy the skin once its relaxed. The fibers will generally break apart, most noticeable around the lips and around the eyes first. Does anyone have any suggestions to relax the skin in hopes to saving it.
