I have a nice piece of hazel that I collected many years ago. Unlike those living in Europe, I spent three years looking for a hazel large enough to use as a walking stick. We may have millions of them growing here, but they rarely get larger than 3/4" in diameter. I want the bark to turn out really nice and keep the pattern that is on it. What is the best way to prepare and protect the bark? All the sticks I've made so far have been bare wood.
