How can I achieve an even finish when applying wood stain?

To achieve an even finish when applying wood stain, make sure to sand the wood surface evenly before staining. Apply a wood conditioner to help the stain absorb evenly. Use a clean brush or cloth to apply the stain in the direction of the wood grain, and wipe off any excess stain to prevent blotching. Allow the stain to dry completely before applying a topcoat for a smooth and even finish.
