Hey Guys I am starting a pipe project. This will be my first attempt at carving briar. I want to leave some of the natural burl on the top of the bowl, how do I go about doing that. Do I use a wire brush to scrape off the bark on the outside or what? I've tried to find some videos but haven't found any. Any help from the pipe artists on here would be helpful, thanks. Here are some pics of my block.
