Ah, ok. Perhaps I could make paper bunting and use photocopied comic pages.......
Here's another one for you. From the blog that provides the super reversible cape, is this about a no sew cape.
"I needed to find a fabric that I didn't need to sew. I eventually found it at Fabricland and it was only 75p a metre! Its almost like paper but much much stronger as it doesn't tear and it also doesn't fray. I simply cut out the same cape shape, attached some velcro and it was a cape ready to go!"
But she doesn't know the name of the material! She melted it to her iron, so I assume it's a plastic type material but both of my local fabric shops have told me they have no idea what I am talking about! Do you know what it is? Could be a type of kite making fabric?
I know I could use felt, but is that not a bit heavy for August? Am I thinking too much about it?
A quick hunt suggests that there is plenty available, but it is not cheap. If making superhero bunting I would be tempted to get a small amount of one of the fabrics with "zap", "pow", etc all over and lots of cheap plain fabric in strong colours (red/bright blue /yellow /black) as well.
