Supplies: Bleach; water; old newspaper, magazines or junk mail; empty squirt bottle; plain T-shirt; scrap paper (a newspaper is perfect); cut-out of the Horde insignia (or your symbol of choice) on a piece of parchment paper (or freezer paper); low-tack spray adhesive; tweezers
Cut out your Horde insignia (or your symbol of choice) and spray it with a little bit of the low-tack spray adhesive. Stick it onto your T-shirt wherever you want. Slide your newspaper into your T-shirt. (I could not find a paper, so I taped all the junk mail from my building's mail room together.) Make sure everything stays flat.
Transfer everything to the tub or the grass. (Unfortunately, it is snowy and cold, so I am doing this inside.)
Mix a 50/50 solution of bleach and water in your spray bottle. (You really don't need much, and you don't want to leave it in the spray bottle afterwards. I did last time, and it ate away the plastic straw inside ... Oops!) Now be careful! Bleach is serious stuff! Quickly spray your shirt. I typically try to spray mostly directly onto the design, to make sure it really pops. Wait a few minutes to see how much the colour is fading. Remember that the shirt is now wet and that the colours will be darker. You may need to respray a few times. The longer you leave it on, the paler it will eventually be. I usually leave it for about 3-5 minutes. Never do know what colour you will end up with.
When you are happy with the colour, carefully (use tweezers) remove the parchment paper and run the shirt under cold water for a long time. When the shirt stops bleeding colour (leave it under a cold tap for a while), throw it in the wash with some other clothes. After it is clean, wear it with pride. There was a rip in the upper portion of my paper, so some bleach got in. Not too bad, gives it an organic look. ;) For the Horde! And swanky gear!
