Unfortunately, it’s not four-wheeled Batmobile we’d all love to take a spin in, but rather a Halloween decoration from Martha Stewart.

Peek into your backyard and your art-supply drawer — odds are you have everything you need to make this bat mobile.

Trace her free bat templates onto black card stock; cut them out and fold them according to template instructions. Make a small hole in the center of each bat with a tack. Poke a piece of thread through each hole, and knot it. Tie the bats to a found branch (painting it black is optional). Then hang the branch from two pieces of thread secured to the top of the window with flat thumbtacks.

One pointer I’d like to add: start keeping your eyes open for the right branch weeks before you start your Halloween decorating. When you find the one(s) you like, bring them into a garage or some other climate controlled area, and let them dry out completely. It’s also a good time to check the branches over for bugs. And if you decide to paint your branch, here’s a great tutorial on the best way to do it.
