Make your own homemade Wood stain

White vinegar can be mixed with water-based inks to make a wonderful stain for wood. The resulting finish is the color of the tint with a silvery sheen.

Pour vinegar into a mixing jar, add the ink until the desired color is achieved and apply to wood with a brush or rag.

Wipe off excess and let dry. Since the bulk of the mixture is vinegar, there is minimal wood-warpage.
