Thanks Jon, The black background is done with the E294 series background tools. The white background is done with the pebble tools from Springfield leather, although I see a similar tool at Tandys (M884), I think its the same tool but not certain.
Im currently learning to airbrush, so I hope I can add more shading and artistic dying and painting to my leatherwork soon.
The hammer logo is from the Sign of the Hammer album cover and depicts a stylized hammer of Thor and the Valkyries wings.
