1. Brown acrylic paint
2. WATERED down black acrylic
3. White acrylic or latex paint
4. Bristle brush
5. Sand paper
Start by dry brushing white paint (meaning take your brush and dab most of the paint off of it and paint lightly across your piece of wood).
Next you are going to put a little black and a little brow on your brush, again dab most of the paint off, and using the dry brushing apply the paint.
Whoah! That looks crazy, right?! Now this is where the sand paper comes into play. Wait about 10 minutes and lightly sand the wood.
Your piece will look similar to this once you have it sanded...
And now you get to make a choice. You can either keep this look or repeat the steps until you reach your desired effect.
Here is my finished product:
