You can buy inkjet iron-on transfers. Google them and a list will pop up where you can buy them, or if you want to be super crafty you can just print out a picture, and paint over it with acrylic paints QUICKLY and before the paint dries, you press it on the the shirt. You will get a reverse image (like a mirror) and you can add on more paint until it is perfected! then to set the paint once it is dry, lay an old towel over the shirt and iron for 3 or 4 minutes, the paint will then be set permenantly.

Post pics of your finished work, I love seeing other peoples designs!
