Crochet Plastic Bag Door Mat

I'm crocheting a door mat out of plastic bags. I cut 2 inch strips and tie them together, leaving about a 2-3 inch tail. I use a J hook and chain the width, then double crochet in each chain, chain three and turn. I crochet each row the same until I have my length. I pull all tails to one side of the mat. That way it has a shag look to it and the other side is flat. When it gets dirty, you can wash it by just spraying it with water.
