Here's a quick and easy one! And now you wont have to greet and say goodbye to people because your rug will do it for you. I've been meaning to make one of these for a long time and was always looking for a plain outdoor rug to do it on, but everywhere I looked they only had rubber ones or ones that had writing on them already. So I decided to just do it on the rug I've had outside for a couple years. Its going to get dirty anyways so I tried it out!
