I took plain, natural wood shutters ( I forgot to take the picture of them in their natural state). Painted them black. Let that dry.
Paint a clear crackling medium over that. Let that dry.
Than I, sloppily, painted a top coat of a different color ( I used a cream color). Let that dry.
As it dries, it will start to crackle.
Voila! My new headboard.
Here's a close up. I love it. We put a fresh coat of paint up on the walls. And now we have a brand new bedroom. Yay!
