They just had to be... bats. I made a wing and body template and traced them onto the foam. I put the template below for ya. There's a baby and momma pattern. Hold the wing tips along an edge to take advantage of the 3-D contour.
Use a pencil to trace. It will leave an indented line for you to cut along.
Flip your wing pattern over to get the opposite side.
Cut little triangles out of the corners for ears.
Hot glue pieces together for instant hang-a-bility.
I stuck them on the porch rails. Maybe I should reverse that though, pumpkins on bottom and hanging bats!
