Little Tip: If you wet the leather and then towel off the excess water you can have a drawing or image on a piece of paper and draw over it, while it is placed on the leather, and the image will show up onto the leather.
Step One: Wet the Leather and dab it off
Step Two: Have an image on a piece of paper and place it on top of your piece of leather
Step Three: Trace the image with a pencil and the image will show up on the leather.
Step: Paint and/or stain as desired.
