How can I achieve a consistent and even application when using thinning water-based stain on my project?

To achieve a consistent and even application when using thinning water-based stain on your project, make sure to mix the stain thoroughly before applying it. Use a clean brush or cloth to apply the stain in the direction of the wood grain, and work in small sections to prevent drying too quickly. Additionally, consider using a pre-stain wood conditioner to help the stain absorb evenly.
