Step 1: Supplies
printer paper (w/computer + printer)
black/dark colored t-shirts
cardboard (not pictured)
tape & scissors (not pictured)
Step 2: Setup
Next, you're going to want to print out whatever you're putting on the shirt, in the size that you want it to be on the shirt itself. In this case, I had letters, but you can put images in there, so long as you feel comfortable tracing over those images later.
Of course, the design may not fit on one line or one piece of paper, so you may have to go through, cut, and tape the paper so the design is how you want it. If you want to use minimal ink, I would suggest adjusting the color so it's something light, but still something that you can see on the other side of the paper if you have the printout against a white surface. In this case, I printed out the lettering in grey rather than black. If cutting and taping produces some overlap that makes it challenging to see through, come in with a pen/marker.
Step 3: Trace
Step 4: On the Shirt
Then you can come in with the fabric paint!
Step 5: Final Steps & Considerations
Repeat this process with all the other team t-shirts. I would suggest doing each step on all the shirts at one time, but you can repeat the process for each shirt if supplies is limited.
Things to consider:
-This technique works with black/darker colored shirts. I *would not* suggest trying this technique with charcoal and a white shirt because the charcoal would be impossible to get out. White chalk tends to rub away easily though.
-It may be a good idea to practice using the fabric paint on another surface before you paint directly onto the shirt. Knowing how to handle the fabric paint bottles can take a little practice, so it certainly couldn't hurt
-You may want to have a paper towel next to you while you are using the fabric paint so as to wipe away any excess that may build up around the tip. This can be helpful if you're trying to paint clean lines, like I did here.
-Wait a few hours before you come in with another color of paint. The paint needs to dry, and you'll be really annoyed with yourself if you mess up the work you did beforehand.
-Make sure you turn the shirts inside out before washing them!
