I'm posting again today since a couple of you asked about my painting technique for this.
I spray painted it with just regular flat white spray paint. The brand I used is called Krylon. Spray it and let it dry. I recommend using flat paint because the glaze will adhere better. To make the glaze I dilute brown acrylic craft paint with water, about 50/50 ratio. The paint is the type that comes in the little plastic squirt bottles that you can buy at Michaels or any hobby shop. Brush on the glaze and rub off the excess with a paper towel or rag. Leave a lot of the glaze in the crevices. On this one I brushed on a little white paint over some of the high raised areas after the glaze dried. That's it! If your piece is going outside I would put some type of clear coat on it to protect the paint from washing off.
