If you're going to use a black shirt, go to your local office supply or crafts store and pick up iron-on transfer paper for DARK shirts (this is very important, LOL). Next, print out the lettering onto the transfer paper (you might need a imaging program for this; if you do, let me know). After that, you'll have to cut out each letter (this can be a pain) and then peel off the transfer backing (it's not sticky; just bit so you can get some permanence). Place the letters where you want them (using measuring tape would be a good idea), put the wax paper over the letters, and IRON! And voila, instant Richie shirt for LOTS cheaper than the original.

Hope this helps!
