Add paint and distress arte metal!

Use shades of blue Sharpie paint markers to color an arte metal medallion and allow to dry.
Add a few dabs of Adirondack black paint dabbers and smear slightly on top of the blue.
Next sand off excess paint along the relief area and allow the silver of the arte metal to shine through. Spend extra time sanding edges to give a more distress look to your medallion.
