Check out Stephen's forehead. He's got a temporary tattoo, and they're very easy to make... You'll need a special kind of printer paper for this. It's called transfer paper and you can get it from art supplies shops and computer equipment retailers. There are lots of design possibilities, as you can see! We've got some designs that you can print off by clicking here. Alternatively, draw your own. Any paint software will do. It's a good idea to create your design in the bottom corner of the page, so that when it's printed, it'll be at the bottom of the paper. Print out, and leave to dry. Cut out the tattoo, leaving a margin around the edge. Now you can peel off the tattoo. It can be quite fiddly, so be patient! Then just carefully apply it to your skin! And when you're bored with your tattoo, you can just peel it off.
