I've been asked to make a couple of cork boards 18 x 24, for our church. They want the cork to be darker in color. I've located a couple of sources of colored cork, but it isn't clear they will deal with the small quantity of cork that would be required for this project. It also appears that the price of colored cork is 3 times (or more) than natural cork. I found a site that indicates that you can apply diluted wood stain to color cork, but no photos showed the actual before and after result.
Does anyone have any experience staining natural cork?
