Si,most, no, I will say all of the Native American work on bows was pure free hand and from the heart. It was intended to represent the tribe and individual man. You will never see two alike, ever. That is what is the best part of native art, it is all interpretation of live and inter connection of man and the land and family. Just go with what you feel, how you see live and the colors that are you, not someone else. From the heart always is the best.
