Do you need a good Irish Coffee Cup?
Buy some white cups or glass mugs. We picked both up at Walmart.
Use an oil-based paint Sharpie markers. Regular Sharpie WILL come off even after baking.
Let the mug dry for a few hours before placing it into the oven. Bake the mug in the oven for 30 minutes at 350°F. Remember to place the mug in the oven before it heats up and leave it in until the oven cools completely so there won't be any cracks. Remember to Hand-wash the mug gently instead of throwing it in the dishwasher.
