Here is a nice photo of a dead Pinus Ponderosa tree limb showing a natural Jin created by mother nature. Natural looking jin is what every Bonsai Artist should strive for. Notice the Bonsai Jin still has bark on the backside of the Jin. International Bonsai Master Bjorn Bjorholm instructs his students to leave a little bark on their Bonsai Jins. RMBS International Bonsai Master Larry Jackel is one of the top Bonsai - Deadwood artists in the world and he is always a good person to ask about Bonsai Deadwood.
