Melt white chocolate in a double boiler or a heatproof bowl set over a pan of simmering water, stirring. Spread white chocolate onto an 8-by-12-inch food-safe plastic wood-grain texture mat (chineseclayart.com) using a small offset spatula. Scrape off excess chocolate, using spatula, until the thinnest layer possible is left on mat. Transfer mat to a baking sheet and freeze until firm, about 10 minutes.

Moonstar if you check the site under food decorations, you'll see that there is a food safe mat that makes a wood grain impression.
I would appreciate hearing from MS staff regarding mat for bark design as it is not food safe.
What you can use are preprinted chocolate transfer sheets. There are hundreds of transfer designs to choose from. They're available from Amazon.com or other on-line sites such as Gobal Sugar Art, inkedibles and Shopzillas. They're easy to use and give chocolates a professional look.
The website for the texture mats doesn't seem to have food-safe plastic mats. In fact, here's what the product description states: "The Texture Mat is a patented clay tool for making textures on the surface of wet clay. The artist or student can use the textured clay to build many different forms. It is only for clay, not for Food."
Has anyone tried this with a wood-grain tool instead of the mat? I wonder if it would work... ?
