This instructable explains how I bleach printed a few t-shirts. I wanted to try a little different approach for making some shirts for the band I'm in. The goal was to make something a little more distressed looking and less expensive. There are bleaching techniques using waxed paper ironed to the shirt on but I was looking to make multiple shirts and waxed paper cut-outs weren't a good option. this instructable will cover the details of how I made the shirt pictured, not necessarily How I mounted everything to the table I worked on. That's really not all that important.
Hope you enjoy!
I scrounged the house for some of the materials and had a buy a few others.
The basic list is:
1 Gallon Bleach - I used a 1:3ish solution of bleach to water
3% Hydrogen Peroxide (used to neutralize the bleach)
1 Pair rubber gloves
1 Spray bottle (to be filled with a bleach solution) - use a good bottle that produces a good fine mist
1 Spray bottle (to be filled with peroxide) - use a good bottle that produces a good fine mist
1 Old plexiglass screen door window
A couple of towels
A couple pieces of cardboard
Blank stencil material (purchased from Michael's)
Miscellaneous "shapes" - I used a paper plate and a larger ceramic dining plate.
Ruler and square
Utility razor knife
2 spring clamps
Blue painter tape
5 gallon bucket for water
Use caution and/or eye protection when cutting plexiglass.
Use bleach in a well ventillated area.

Step 1: Cut the Plexiglass
I had an old plexiglass screen door window in my basement. The stencil is 8" x 10" so I cut a square opening in the plexi about 9" wide by 7" tall allowing 1/2" around the edge to tape the stencil to the plexi.
To cut, mark the edge of the opening and score as deeply as possible with the utility knife (multiple shallow passes works better than pushin' real hard). I got impatient so I drilled a couple of holes to accomodate my little hack saw and cut it out on 3 edges. Use the small hammer to tap along the score to crack the plexi loose. Use snips to trim off any jagged edges.
Step 2: Finish Off the Opening
Use a metal file to clean up the edges of the opening in the plexiglass. There may be some extranious cracking. It's ok because it'll be covered with tape. When cutting and filing are done, wipe the plexi with a rag to remove the little bits and pieces and dust.
Step 3: Mounting and Hinging
I'm not going to go into detail about the mounting and hinging because it is very makeshift and not critical to making the shirt.
Quick & dirty steps:
Find a couple hinges
Line up and mount hinges to window frame and board (notch board as needed)
Square up and clamp board to table.
Step 4: Attach the Stencil
Line up the stencil under the plexiglass. Tape the stencil to the plexiglass with blue painter's tape. It can be easily removed (in most cases). Lift the plexi and carefully tape the back side as well.
Step 5: Place the Shirt and Spray
Line up the shirt under the plexi and lay it down. The first run, I overdid it a little on the bleach and it bled under the stencil. Plus the shirt is thick enough that it make the plexi flex a little causing the center of the stencil to lift off the fabric. This can be countered by making sure to pull the stencil tight when you tape it to the plexi and by placing small weights on the plexi to press the stencil down (cans of veggies would work).
When you're lined up, set the spray bottle to the finest mist it will produce and spray away. It took about 8 or 10 pumps to thoroughly wet the fabric. Let stand for 10 minutes (longer if you want a more pronounced bleaching effect.
Remove the weights and use a towel to blot up some of the bleach on the suface of the plexi and stencil.
Step 6: Have Fun With Shapes
I laid the dinner plate down and misted the bleach around it. I removed the dinner plate and laid the smaller paper plate inside the ring. I set the spray bottle to a coarse stream and lightly sprayed randomly around the edge to create a more distressed blotchly outline.
You could use anything to create additional shapes. Nylon string would be fun! After about 10 minutes, spray with hydrogen peroxide to neutralize the bleach and rinse the shirt in clean water.
Step 7: Wash and Dry
When satisfied with the level of bleaching, spray the bleached areas with 3% Hydrogen Peroxide to neutralize the bleach. I have read that peroxide is safer to use than vinegar for neutralizing bleach and it doesn't smell nearly as bad. The peroxide seems to neutralize the bleach faster than vinegar too. Let the peroxide sit for a minute or so and then rinse thoroughly with water. Here's the finished product.
