A wiki entry almost seems redundant in a way...symmetrical design, get creative! How do you envision this mushroom? Draw half of it (with a washable marker) on a folded in half shirt. Not sure? Play around with drawing mushrooms and folding them in half to see what you want there, make a stencil if you want Remember that there are different kinds of mushrooms, be sure to think of the features that make the kindo f mushroom you are trying to achieve *that kind* of mushroom (little skirt, thin flat top vs chunky salad mushroom type, choices in coloring) or make a totally fantasy mushroom that simply looks cool.
If you did want an eye in the mushroom you would then draw the eye half as well.
Fold it up! That's really it. The sky is the limit on this stuff, if it is symmetrical, you can conceivably make a tiedye or it.
