1) Figure out the graduation year and print 'class of 2025' in a large font on your computer. Cardstock will work better but I used regular printer paper because it is all I had.
2) This was the hard part, cut out the letters. I used scissors and took my time. You might want to try an exacto knife if you prefer it. Also make sure you don't cut out the middle of the '0'.
3) Place a large box inside of the shirt. Make sure the shirt is pulled tight so it can't move. Then tape the printed paper (your stencil) to the shirt. You may want to tape more pages around the outside to make sure more of the shirt doesn't get painted.
4) Spray away!
