Two of the girls are mine, one is 8 and the other 11.
The cloaks and boot coverings were made from twice dyed calico (terracotta and brown in a tie dyed sty-lie), The masks were made from tactical night sight head gear, which allows the front to be lifted up. The diodes were powered by 3volt batteries and sit behind yellow lences, very bright.. I'll dig out some photos or you.
The blasters were commissioned from a guy in Essex, £65 quid each.
The WW1 Enfield ammo belts came from South Africa £25 each.
The droid caller is an adapted resin model, with push switch, buzzer and battery fitted after the body was drilled out.
Plain black gloves with fake fur.
I also made jawa FX's that are run from an mp3, through a power amp (9v) to a speaker operated by a pressure switch strapped to their fingers.....very funny when all three are jabbering away.
Total cost about £200...well worth it
If you need any further info just let me know.
Cheers
