First Things First
Step one in organizing your Halloween party is deciding what kind of party you are going to have. Are you going to have a themed party or just a fun bash? Is it going to be a potluck or are you going to try to do it all yourself? Hint: Trying to do it all yourself not such a great idea. It makes your life a whole lot easier and allows you to have more fun if it is a potluck. Believe it or not, it can also make it more fun for your guests. Some fun potluck ideas: Have everyone bring the most disgusting looking or sounding dish that they can find. However, make sure that they know it must be edible! If youre doing a themed party, have everyone bring something in keeping with the theme. For example, for a pirate party, have everyone bring a dish that has a skull and crossbones in it or on it.
So first decide what kind of Halloween party you are going to organize and how you are going to handle the food.
Make a List
Step two in organizing your Halloween party is making a list of everything that needs to get done. Just sit down and brainstorm everything that you can think of. Then go back over your list and figure out the order of what needs to get done. For example, sending out invitations should be one of the first things on your list. Organizing and buying decorations should also be near the top. Getting food ready will be at or near the end of the list. Then go back through that list one more time and organize it one step further by figuring out roughly how long each task will take you. Hint: It is better to overestimate the time it will take you than to underestimate.
Get Ready Before The Day
Okay, so this is more of a tip than a step in getting your Halloween party organized. But it is important so bear with me. In order to minimize your stress and to make the party more fun for you, get as much as possible organized before the actual day of the party. This includes making as much of the food as you can before the day of the party. If you can make it and freeze it, by all means, do it. This also means cleaning whatever areas of your house you feel need to be cleaned beforehand. A few more things you can do before the day of the party: wash dishes, decorate, setup tables and put out anything non-perishable the night before.
And the most important tip of all: Have FUN!
Happy Halloween!
