Anyone ever stain a natural cob? If so what stain did you use? I read where some like leather stain but I was contemplating an oil based wood stain (I have some in the garage ). If you stained it did you also finish it with a shellac or poly? I really enjoyed my cob hiking the other day and I am thinking of getting a couple more to have around the house/car/toolbox/tacklebox/fishing vest, etc and I like to tinker and was just wondering about dressing a couple up.
