Backstory: There are three PT Cruisers that are cool vanilla that go to my nephew's school, besides me, to pick him up in the afternoons. He's had a slight problem picking the right one, so I needed to do something easy, cheap and not permanent to distinguish mine from the others.
On the way home the other day, we stopped at a drug store to get drinks and snacks and at the checkout I saw these polyethylene straps people use to keep their glasses around their necks. Perfect diameter, bright and colorful, a $1 each.
It's so ugly it's funny, but effective and I can change it easily when I want to without feeling guilty.
