heres what we've decided to do:
Invitations: Printed of the 'superman' crest/logo in colour, DC cut them out and stuck them onto coloured cards.
Costumes: we asked people to come dressed as their "favourite super hero or their own Super Alias" - that waye people don't have to go out and buy expensive costumes for their kids if they don't own them - just a cape will do).
Decorations: will either just do normal coloured balloons, or may go with red/blue/yellow as superman theme colours (not that DS has ever seen superman! He does recognise him though).
Cups/plates: I got sick of buying and throwing away plastic party ware a couple of years ago, and so we now own 20x childrens ikea cups and plates. Not bothered about co-ordinating as the kids don't notice anyway!
Games: Have cut it down to a few -
Obstacle course - kids have to put on a cape and mask, then run and leap over a "tall building" (cardboard box painted to look like sky scraper), then run and lift some heavy weights (ppier mache or black balloons on ends of stick) 10 times, then climb a (step) ladder and rescue a damsel (soft toy), then use their super powers to open a box with a pirze inside (chocolates).
Pinata - DS's favourite game ever. We will just tell them to use their super powers to break it, or, if they'd prefer, a stick.
Musical Super heros - we have the supeman music on a "classi FM at the movies' cd. every child gets a little prize when they get out, winner gets a more substantial prize.
Food - am not bothering with theme I've decided, as am too knackered with this pregnancy and I don't think the kids will really notice. Will cook mini pizzas, and do sandwiches, water melon and grapes, and a crisp/crackers/crudites and dip platter.
Party bags - have bought some superhero magnets/erasers/sharpeners etc, each child will have one of them, a balloon and a few sweets.
Done!
Intitations went out on Monday! Hope it sdoesn't rain...
Thanks for all your help :)
