I made the bats from Martha Stewart last year for Halloween, which I've kept for this year. I chose to simply cut the bats from black felt using the template and then hang them from the ceiling with fishing line from different heights. I attached some with fishing line directly from the center so the wings would hang down, and others I attached fishing lines to the center and either side of the wings to create variety and give the effect of bats in flight. Besides the cutting, which takes a bit of time, they were really easy, really inexpensive, and made a big statement! I can't wait to use them again!
