Some times when we whittle or carve wood there ends up being a part of the carving that is thin and fragile. This is especially true when a part of the carving has the wood grain causing the weakness. This is what happens when you carve figures with a hat and a hat brim. Most of the time we carve the figure so that the wood grain runs from the head of the figure to the feet. And that means that the hat brim will not only be thin, but very weak, because of the wood grain direction.
