This is a wall. To the left of the wall is my wife wearing a red shirt.

She really digs the shirt because it's super soft. She doesn't dig the words on it that much.

It was a freebie swag shirt, so we'll forgive the corny copy. Still, America's kids aren't exactly her mission. So, I offered to paint over it.

I wasn't sure what I wanted to print, just that I wanted to cover up that section. The paint was printed lightly into the fabric in the typical faux-worn out style. Not difficult to cover up, but I would have to use black.
I stared at the cover-up shape for a minute until I decided to make an umbrella out of it. My wife is into minimalistic stuff, so I thought a simple icon would do the trick. Turned out to be the easiest stencil I've ever made.

This is how it looked lined up on the shirt. I lathered the fabric paint on thick to make sure the words didn't show through. The nice thing about simpler shapes like this, as opposed to my typically more elaborate stencils, is that no matter how much paint I use, almost all of it ends up on the shirt and not all over a sheet of cardstock.

And there you have it. You can barely see the words beneath the paint, but that's with flash photography and an eye that already knew they were there.
And in case you were wondering: she loved it.
