No, it's not Batman's car! It's a mobile with not-so-scary little bats made from Smoothfoam! They are so easy, you'll have them fluttering all over the house. The wings and ears are re-used plastic lids! Here's the link to the instructions on the Smoothfoam blog.
The Creativity Team at Smoothfoam (of which, I am thrilled to be a part!) is having great fun with this theme and you will too as you decorate your house for Halloween!
