One option you have with black walnut is to request that we "sap stain" the top to reduce the color variation. This will tone down and even out the contrast of light wood to dark. This choice should be given careful consideration. Natural variations in the color of wood, especially walnut and cherry, are not considered a manufacturers defect. Additionally, we do not stain to match other items or samples. The purpose of sap staining is to reduce the natural color variations and should not be thought of as a traditional staining process. No choices of stains are available and the degree of staining is at the sole discretion of the Wood Welded Companies.
