Clean the surface with mineral spirits and a lint-free rag or cheesecloth.
Dip the cheesecloth into the wood stain. Wipe a thin layer of stain across the surface. Keep the layer uniform in coverage. Do not allow stain to pool in the corners of your project. Use a paintbrush to spread the stain outward from the corners.
Place the wood graining tool at the edge of the surface. Apply pressure with your index finger and pull the graining tool toward your body, moving at a steady and constant speed.
Rock the tool back and forth gently as you pull the tool toward you. If you are using a comb or a roller, pull the tool through the stain at a steady and constant speed.
Allow the grain to dry, 16 to 24 hours.
Wipe on a thin layer of stain to fill in the wood and accent the stain. Apply more stain to create a thick rich wood stain although this will reduce the prominence of the graining.
Protect the finish with a top coat of polyurethane. Use interior polyurethane for indoor projects and exterior polyurethane for exterior projects.
