So I have a request to do a multi layer sign with two tone staining on cherry wood. I'm thinking there is a problem. If I do say a darker stain on the background and leave the lettering natural, once the cherry naturally ages and turns dark it won't look as good correct? Has anyone done this before? I would have to stain pretty dark to still have a contrast in say 20 years. No matter what finish I use it will not prevent the natural aging. Thoughts and suggestions? I think I will have to suggest a different species.
