Anyone remember this show from back in the late 80s??
We bought the shirts online (I'm not creative enough to make my own shirts when it comes to this kind of thing) - although the rest of it was easy to put together. We went to a sports consignment store - not a wide range of bike helmets but we made them work (it's amazing what a little yellow spray paint can do to cover up a kid's Dora the Explorer helmet! :)
I used glue dots to attach the cheap dollar store cups (painter's tape for the line around top) and they held up quite well. The elbow pads were also purchased pretty inexpensively from the consignment store. A pair of $1 safety goggles to complete to look - and there you have it. :)
Hope you have a wonderful safe Halloween!!! :)
