I can do this with the Sharpie idea. Sharpie design on mug, bowl, plate, or any other oven safe glass object! 350 degree oven for 30 min, and there you have it! Instant art to display your tea + coffee + yummy food in.
Weekend DIY Project: Decorate a mug or cup -- Bake in the oven for 30 minutes at 350 degrees. Let it cool completely before using or washing it. When you wash the mug, hand-wash it gently instead of throwing it in the dishwasher.
