SCRATCH BOARDING ~men love this technique! I choose to do mine on a clay board instead of paper. Basically the board is covered with india ink and you use a tool to scratch the surface removing the ink layer to reveal the underneath white clay board surface. You can also go back and recolor that area with inks. Being a lefty, I am looking for a variety of tools as the edges of the commonly sold blades are often slanted for the right handed person.....
