1. Black ink. Scratchboard is a notoriously unforgiving medium, but mistakes and corrections will inevitably occur. When this happens, I use either Daler-Rowney black ink or Faber-Castell Pitt Artist Pens to reapply the black ink onto the board.
2. Lighting. Having good lighting is essential when working with scratchboard. I use two daylight desk lamps that can be adjusted to numerous heights and angles with variable degrees of warm and cool light depending on my need. I prefer to keep my floor space clear and opt for the desk attachable versions.
3. Slice tools. Slice offer some great tools to be used with scratchboard art. They feature ultra-sharp ceramic blades that allow clean, crisp lines to be made. Because they are ceramic, they can remain sharp for up to 11 times longer than traditional steel blades.
4. Ampersand scratchboard. This is my go-to surface for creating scratchboard art. It is a white kaolin clay coated hard panel with a coating of black India ink. I use sharp tools to scratch away the ink on the surface to reveal the white underneath, allowing for amazing fine detail and stunning contrast.
5. Tattoo needles. I use tattoo needles in every single artwork I create in one way or another. They come in various sizes/styles that can be great for creating the initial base layers of fur.
