Start off with a natural fiber door mat. Purchase from any local hardware store. I got this one from WalMart for about $7 bucks!
Next, tape off your border. I just did 8 long pieces of tape and the used my knife to cut out the overlap.
Then, print out your initial and cut it out using a sharp knife.
Use spray adhesive to adhere the initial to the mat and go bananas with black spray paint.
Pottery Barn's for $76.00. Mine is way cooler!!!
