Another important part is the favors you will be giving your guests. Not many people give favors at a housewarming party, but it is always a good gesture to do so. After all, these people are only coming to adore your new home. The favors, again, need to be in accordance to the theme you have decided. If you're not going to have a theme, you can give away favors that symbolize good luck, such as a potted money plant.
