Supplies:
Blank Door Mat (I found this one at Ikea for around $10)
Spray Paint
Masking Tape
Stencils
I started by spray painting the entire mat a solid color.
Allow paint to dry thoroughly. Then you can be creative and use the tape and stencils to make your own design. (I tried to use the blue painters tape, but it would not stick down. I found some masking tape, and it worked much better.)
Then take your other color, and spray paint over the top of your tape. Spray until you can't see the bottom color anymore. Wait until it's dry, and then remove the tape. Removing the tape is always my favorite part! I usually can't wait for it to dry, and end up with paint all over my hands!
Ta-Da! You have a new door mat!
