I had these glasses lying around from a party I went to a while ago, and since they were just collecting dust, I decided to do something to them to make them a bit more fun. I'd seen people who'd put lace over the lenses of sunglasses before, and I thought I'd try it out for myself, adding a different take on it.
Start with your plain pair of glasses.
Cut out your bat symbols from lace. I added a coat of Modge Podge to the lace first to ensure that the lace held its shape.
You should now have two lace bat shapes.
Add a tiny amount of Modge Podge to the back of the lace bats, and attach them to the lenses of your glasses.
