We put a little tea set in the sand pit so that the toddlers could host their own Mad Hatter's tea party.
The Cheshire Cat I painted was used for a "pin the smile on the Cheshire Cat" game.
Alice plays croquet with the Queen of Hearts using flamingos. Ideally, I'd have liked to have bought proper croquet mallets and painted them to look like flamingos. However, I couldn't justify the cost (our garden isn't very croquet friendly being hilly and slightly downwards sloping so a croquet set would not get a lot of use). So we made our own using some scrap wood and thick wooden dowelling (total cost: about £3).
These are the party bags we sent the kids home with. The girls each got a little Cheshire Cat purse, but the boys ended up with Doctor Who and Spiderman items as it was difficult to find Alice in Wonderland themed stuff to suit them! There were also prizes for the games such as an Alice in Wonderland Audio and book set (only cost me £2!). The party bag fillers all came from a site called Mummy Martin's Toy Box.
