Sand the wood handle of the hammer to rough up any coating that may have been added. Paint one side of the wooden handle white. Once it’s dry, paint the other side white.
To monogram the hammer, paint the first letter of dad’s name toward the bottom of the handle (T for Tom, B for Bob, etc).
Decorate the rest of the hammer in whatever fashion you like! You will need to paint one side, let it dry, then paint the other side. Let dry completely.
Use a black fine point marker to add any details, such as outlines. It’s important to let the marker dry for a good 30 minutes, otherwise your sealer may cause the marker ink to bleed.
Spray with a clear sealer or glaze. Let dry and repeat for a second coat. Allow to dry overnight.
