I hadn't bothered to replace the ugly Home depot standard issue door mat on our back patio since we've moved in, which is kind of sad since the ugly mat was in plain view of our eat in kitchen.  I picked up an inexpensive boring mat today and marked it off with painters tape into a Union Jack design, before coating it with satin finish spray paint.  It cost me under $10 and took about 5 minutes. What was I waiting for?
