DD's party idea is for every guest to 'adopt' a soft toy.
I've got a load of iedntical puppies and put a different colour ribbon on each. So far I have made a pass the parcel with a matching ribbon in each layer, to denote which puppy they get to adopt. I have some pendants to hang on the ribbons to make necklaces for each guest. Adoption cetificates to fill out with puppy's name.
Then a picnic tea on the floor.
I'll need some more activities though. Any ideas for games, crafts etc? And a 'back story' for why the puppies need a new home!
