I knew I wanted something round for this project and these snowglobes had almost identical bases and figured they'd work great!

I scuffed the glass and then spray painted both so that the glass was completely covered.

Light a candle stick and place a fork in the flame. Notice how the smoke turns black. This is what we will use to add the marble to our base paint color.

I put the candle on a candle holder so I could have a free hand. Hold the globe in one hand and the fork in the other. Hold the globe about 8 inches above the lit candle.

Place the fork in the flame. Roll the globe around in the black smoke as you want it to land on the product.

Note that the closer you get the more black the markings will appear.

Sealed with a spray on poly!
