These ones were rather fun. An old tree from the local graveyard had broken and fallen during a storm. There were pieces of its bark, solid, clean, smooth and perfect which I gathered up a good armload's worth.
Basically, I was crafting these into unique altar plates to sell. I used a wood-burning tool to define the images and then painted them with acrylics mixed with metallic paint.
More examples to come. :)
The following are a gathering of various "wood" pieces which I have done.
