Both of these drawings are made with Litho-Coal Erasable Sumi Ink. They don't make this anymore as far as I know and the bottle of solvent I had somehow dried up. So...I used water with a little bit of dish soap. Probably will work better once I get some alcohol. The last time used the litho-coal product was for my poly-litho "Tree Hugger". Unfortunately, I don't really have the facilities here to do any litho but I really think either of these would have made fantastic prints...
