Pat if they are smoked good it won't take a lot to get the soft again, just dry them a bit after washing and stretch them across your lap, pulling in all directions.That is what the smoke does, water prof to a certain extent where when they get wet they don't dry stiff, UN smoked ,they will dry stiff if they get wet but the creosote in the smoke gets between the fibers and keep them from binding back together. Some think you smoke for color but the main reason is to water prof.
