Hi there. I know there's a variety of official and custom-made cowls and masks available through a variety of sources. And then there's the DIY-cowl messageboard Brotherhood Of The Bat where people give tips on making there own costumes, props, cowls and such. I have two questions: - Does anyone know of any other DIY cowl/costuming sites besides BOTB? - Does anyone have any recommendations on turning a bicycle/motorcycle helmet into a custom Batman style mask/helmet? Any recommendations, tips, links, etc. are much appreciated.
