You'll need:
- Your imagination :)
- Printable window clings (available at Walmart, K-mart, etc.)
- Color printer
- Graphic program like Print Shop
This is a craft that you could use permanent markers if you did not have a computer or color printer. You can make stickers from window clings to stick on your car windows. I don't like the idea of putting a permanent bumper stickers on my car and this allows me to put a window sticker on my car and remove it any time I want.
Using a graphic program (or your imagination and permanent markers), create a bumper sticker. Print it out, cut and place on your car window.
