- Black tshirt.
- Scrap cardboard.
- Razor knife.
- Spray bottle.
Step 1: Image
Cut along the symbol out and place it on top of your cardboard. Trace around the Pi and cut out with utility knife. Be careful. Seriously, don't rush!
Step 2: Shirt Prep.
Position your Pi stencil and time to make the spray solution.
Mix 3/4 c. bleach to 1/4 c. water in a spray bottle.
Step 3: Magic! Okay, the Bleach Solution.
Remove stencil and allow your shirt to sit. Keep cardboard divider in place. This is the sketchy part. The actual time depends on the type and quality of your shirt. Don't set it and forget it! Keep a roving eye on it from 8 minutes on. If overexposed, the bleach will eat holes in your shirt and that's a bummer!
Rinse thoroughly with cold water and tada, festive Pi Day attire!
Happy Making \m/
