2015-11-08 (Su) Bleached CYBORG Shirt COMPLETED

A temporary hold has been placed on the Chording Keyboard. My job has redirected me to another state to do some work. I would have written the Instructable from my hotel room, as I've done in the past, but I didn't have the energy to do a good job. Instead I'm pulling out this goody from a cpule months ago about making custom t-shirts but not with paint.

Enough background.
3D printed letters were saved from the last custom shirt which was made by applying spray paint over a masked area so the resulting pattern was an inversion of the mask. This is not a new idea but the Instructable which caught my eye made the procedure seem pretty easy. It was easy.


  • Dark t-shirt
  • Paper bag or piece of cardboard large enough to fill t-shirt
  • Bleach
  • Water
  • Pattern
Patterns can be anything from vinyl decals, masking tape, or, in my case, 3D printed letters.


First thing to do after gathering materials is mix a solution of 1/2 bleach and 1/2 water. Tap water is fine. My shirt used about 2oz (60mL) of water-bleach.
Second thing to do is put something relatively stiff into the t-shirt. This will do two things. It prevents bleach from affecting the back of the shirt and it keeps the shirt flat.
Third step is to apply the mask. As shown in the next picture the letters are simply arranged on the shirt. If this is your first time you may have to but the design higher than you expect or the design will be over the stomach instead of the chest. Unless you want that.
Fourth step is to spray the water-bleach solution over the shirt and mask. Be sure any large droplets from the spray bottle are caught in a paper towel. If you get bleach on your hands wash it off after this step.
Fifth step is to let the bleach sit for a few minutes. I let my shirt process for five or six minutes.
Sixth thing is to put the shirt into a water bath. This dilutes the bleach and stops it from affecting the shit further. You can't overdo this step so spray it was the shower or a garden hose.
Lastly wash the shirt in the laundry or at least dry it.

To summarize:

  1. Gather materials
  2. Mix 1 part bleach to 1 part water in spray bottle
  3. Stuff shirt
  4. Apply mask to shirt
  5. Spray shirt with water-bleach
  6. Allow bleach to process. 5-6 minutes
  7. Put shirt in water bath
  8. Wash and dry
