Make sure everybody knows WHEN and WHERE the carnival will be by advertising. Here are some ideas:

Posters. Make colorful signs that tell people about your carnival. Click here for a poster you can print out and personalize . Tell the date, time, location and all the things you’ll have: “Games! Prizes! Food! Entertainment! Silent Auction! etc.” The more posters you put up on telephone poles, at school and at nearby businesses, the better.
Word of mouth. Tell all your friends and their parents. Go through the neighborhood letting people know the carnival is about to begin.
Fliers. Hand out information about your carnival to everyone you know. Click here for a flier you can print out, color and personalize. Be sure to include the date, time, location and what kinds of things you’ll have at your carnival.
Newspapers and newsletters. Your local newspaper, or church or school newsletter may run a free announcement about your carnival. Be sure to include the day, time, address and that the carnival is to benefit MDA.
Be a human billboard. Click here for badges you can make and wear that advertise your carnival.
