For my rustic farmhouse look, I made chalk paint from Behr’s Foggy London paint I got at Home Depot. I used this recipe.
I dry brushed the paint on the wood. I kept coverage light leaving parts of the wood grain coming through. Only get a little paint on your brush at a time and stroke over the wood without reapplying paint until your brush barely yields any more paint. This will create a textured look.
*I demonstrate this technique in my video below.
