1.Print a cartoon picture that you like or you can even tear a page from a coloring book.
2.Tape down the styrofoam onto the table or floor with the picture on top of the styrofoam and slightly trace it enough for you to see the line.
3.When done,take out the picture.Using a dull pencil,trace again the line in the styrofoam.This should look like the picture below.
5.Then you're ready to paint using your roller paint.
Easy peasy right?You can even make a greeting card out of this.So cool!
