It can be done by adjusting the stain to the top. Its just a matter of if the builder will actually do it. A few people have actually gotten pieces of wood sent to them to pick from. Its why I always specify it in my request before I get a price, so that the time involved will be taken into consideration. I do not want to open up that bag of worms again though. It can be done, its all a matter of if it will be. I would rather pay for a few extra hours of the stainers time and get it dead on if that is an option. Again, that is why I make sure to state it before I get a price, not after, like some of my customers do to me.
