Party planning is something that is common and done by almost everyone. At some point, each person has thrown some type of party, whether it is a sleepover or a proper social event. My info-graphic is inspired by 21st, as this is the season where a new party is thrown every week, and when each party follows a basic layout.
For 21st, and other events, alcohol and food are supplied unlike BYO parties. This means that alcohol and food have to be planned, adding to the party steps involved.
Other elements that have to be organised are gazebos, hired glasses, caterers and decorations. These are all steps that have to be planned in advance.
I found several different articles online about what steps are important when throwing a party, and have chosen several simple ones to communicate to the audience the basic elements behind party planning.
