Pinterest Experimentation

I have a pair of nice jeans I got at a swap recently. They fit me just fine but the zipper always goes down by itself. I can't figure it out, pretty frustrating. I came upon this nifty idea on pinterest and I am very happy now with my jeans! You take a key ring, put it on your zipper, then you are able to loop that ring around the button as an anchor! No more falling zippers!
