Things You'll Need
Instructions
Measure the mug you plan on using. You need to know how high your picture can be.
Upload the picture you want to use to your computer. If the picture isn't from a digital camera, move onto the next step.
Print your uploaded picture on a piece of printer paper. Make sure your have a color printer for this. If you have a paper picture, you can take it to a store such as Staples and copy it onto paper. The color copiers run around $.49 a copy.
Cut out the picture with a pair of scissors.
Apply the picture to the mug with Aleene's Instant Decoupage Medium (see Resources). You want to use this particular brand because it dries instantly and is water resistant, which means your picture will stay on the mug even when it is washed in the sink with soap and water.
