As an interior designer, I always recommend approaching party decorations with the same mindset as designing a space: focus on layout, lighting, and harmony. Using a Room Planner, you can digitally experiment with your furniture placement and decor arrangements before your event, ensuring both function and style seamlessly blend for your celebration.

Tips 1:

Choose a color palette before starting to decorate, as it brings visual cohesion to the space. Incorporate unexpected elements, such as ceiling decor or interactive zones, to surprise your guests and create a memorable atmosphere. Don't forget to leave space for movement, especially if you plan on dancing or games!
