Apply the 'snow effect' paste to the top part of the wooden board. Paint the top strip black and the next strip gray. Paint the bottom strip gray too. Also paint one of the sides of the stars gray. Applying the crackle-effect medium/paint: feel free to try out the crackle medium and the acrylic paint together beforehand to test whether or not they produce the desired effect. The thickness of the coats and the direction in which the paint is applied will influence the extent and visibility of the cracking. Still using a paintbrush, apply a uniform coat of crackle medium onto the wide black strip (the paint must be already dry). You should paint horizontally, in single, even strokes ...or not, as the case may be, depending on the effect you're after: the thicker the layer of crackle medium, the bigger the cracks will be.
