I have been complemented many times over the years on my wood texture. So I thought I would show some how-to images.
We use a material known as Signfoam or HDU, its been cut in strips and screwed to an aluminum tube frame. I start by rounding over the edges with a sander and then use a chisel to carve in some dimensions.
The chiseled dimension is just to give some shape to the wood and can be anything from knots to branches.
The next step really add the magic to the texture. I use a cone shaped sanding bit on the Dremel to add small wavy groves and details.
Finally I add some roughness with a file or sharp edge.
