Something fun I did for a Mad Hatter themed bridal shower I did. I transformed my garage into the Mad Hatter's house. I wanted to have the party outside but it had been raining for several days prior to the shower so I moved it inside the garage. I strung tons of ribbons, fabrics, string lights from the rafters and hung teacups as well.

Get great Mad Hatter Tea Party stuff at thrift stores or rummage sales: Mismatched tea sets, plates, and glasses. Plain tableclothes or lace curtain panels that can double as table clothes. Old platters and serviceware (especially if it's silver). Make your own cake stands with large dinner plates and tumbler glasses and some craft glue. Sprinkle playing cards on the tables. Tape the Queen of Hearts on the bottom of a plate and that person gets a door prize.
