Make a t-shirt in the style of a Rorschach ink-blot. The resulting design will be essentially random but laterally symmetrical.
Step 1: Materials
- a t-shirt; either white or light-colored
- a piece of corrugated cardboard, roughly the size of your t-shirt
- t-shirt paint; black or other dark color
- thumb tacks or a stapler
Crease the cardboard lengthwise down the center.
The thumb tacks need to be flat. Push pins won't work. Staples might work if you don't have tacks.
