Zero artistic skills? This is the project for you!
I made this a how-to although i don't have photos to go with the steps :(
This drag art was made the one day in my 11th grade art class when i had some extra time to experiment with paint. Hope you enjoy and please comment if you cant understand the steps. I will try VERY HARD to get some pictures for the steps.
Start by squirting globs of colorful paint on one end of your surface. If the paint is too thick add some water to dilute it for easier spread.
Take the flat side of your strip of cardboard and drag the paint towards the other side. Repeat on all sides to disperse the color where you want it.
For a cool texturized effect, try using a strip of cardboard with uneven edges! :D
Let it dry,
or toss it.
