Step 1: Prepare your text as white on a colored background. Make a duplicate copy of this window and set it aside.

Step 2: Using the Pen, Pencil, Chalk or Crayon tool, scribble across the lettering using black. (Use black for your initial practice, but you can play with using other colors as you experiment more with this technique later.) Disregard the letter boundaries except as basic guides. This is one time you definitely want to color outside the lines.

Step 3: Copy the second window and, letting the white be transparent, paste onto the window you've been scribbling in. Carefully align the lettering. The color background will cover over all the "outside the lines" that were scribbled, restoring the original edges of the letters.

Step 4: Change the white to match your background color and what remains is your scribbled "grunge" text!

Variation: Instead of scribbling in Step 2, use the Pen tool and try outlining the letters -- imprecisely -- and skip Step 3. You can leave your work as an outline or fill it in solid.

However you choose to go about it, your work will be "one of a kind" -- which is what all your artwork is when you're making your own from scratch!
