Laser Etched Drinking Glasses

Step 6 Coat the glass

Cut out a small piece of paper towel. Soak it in water and the wring it out and then carefully reshape it so that it is flat.

Place this paper towel around your glass. Smooth it out to get out any bubbles, but be careful to keep this off the edges of the glass as well, as it will interfere with its rotation.

Also, be careful not to let the paper towel overlap itself as this may alter the results of the etching.
