Dry Scratching Watercolor Technique For Painting Fur
After the painting is completely dry, hold a pocket knife at a 45-60° angle to the paper and start scratching with the blade’s tip, always starting from the white areas and ending in the painted areas. Rotate the paper when you need more control, and scratch in even, controlled, and tapered strokes that vary slightly in length and width (depending on how long the fur is). Scratch over the same area until the white paper shows through; it’s better to gently scratch the same area several times than scratching too hard once and causing the paper to tear. Keep brushing off any residue to keep a clear idea of where you’re scratching.
