It's almost Pi Day!! Fly your geek flag proudly in this festive black shirt.

- Black tshirt.
- Scrap cardboard.
- Printer
- Computer
- Scissors
- Razor knife.
- Bleach
- Spray bottle.

Step 1: Image

Find a suitable Pi symbol of your choice online and print it out.
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.

Take a piece of your scrap cardboard and place in between the front and back of the shirt. Where your body would go. ;-)

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.

Spray generously around your stencil. I went with central overhead sprays in the beginning. My uber cheap spray bottle dripped and I didn't like the large droplets. I found angling the nozzle and focusing on each section of the stencil much easier.
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/
