I have two small bear hides that have been soft tanned that I want to mount, one full body and one for head shell than rugged. I do not have any measurements on the two hides. All of the mounting that I have done has been on wet tanned hides. Do I soak these hides to rehydrate or just moisten them with a spray bottle ? Can I wet them down to restreach for measurements than freeze till I am ready to mount?
