Invitations Create cards with the time, date, place and other party details on the outside cover, and the "you're invited to a backward bash" on the inside. Ask your guests to show up with their clothes on backwards. Décor Hang balloons from the ceiling with string. Erect a "yadhtriB yppaH" sign. Place silverware and dishes under the table. Food & drinkServe cake and ice cream first (kids will love you for it, even if the parents don’t), followed by your main dishes, and finally appetizers.Pour hot chocolate for dessert, and cold drinks later.Upside-down cookie and cone birthday clowns are perfectly quirky.Fun & Games Play "cold" potato instead of "hot" potato. It's the same rules, except you pass the potato when there's no music, and the person holding it when the music starts is out. Also, try "pin the head on the donkey", and "seek and hide," where one person hides and the rest of the gang must find them.
