KAPOW. This costume is super super easy. You can whip it up in 20 minutes flat and all you need is a bin liner, some felt, elastic and a couple of pipe cleaners. Our little ones were so enthralled with it that they flapped around the garden for a whole hour pretending to save the world. See our video tutorial for how to make it below. If you like it, please give us a little like on You Tube and share the love!
