There are MANY ways to complete this project, many mediums, colors, and well... shapes? You could just fill the whole paper with the first tiny design, which is very easy, but I was too lazy for this tutorial.. =]
Start with a blank sheet of paper, pick out a marker or a drawing utensil.
Then draw the outline of a goober on the corner of the piece of paper
Now, inside the goober, draw other random goobers, about the same medium size.
Next, add smaller goobers, about two per random shape, inside of them.
Ahh, now your finished with that piece, now, create another random outline away from the first, and repeat steps 1-4.
OH! And While your repeating, make the shapes larger, and do not fill them in as much, using less color.
Finished Piece! =]
