3. Galactic Balloon Bouquets

Craft eye-catching balloon bouquets featuring metallic silver, gold, and black balloons accented with star-shaped or planet-themed foil balloons. Arrange them around the party area to add dimension and visual interest.

4. Cosmic Table Settings

Set the scene for an otherworldly dining experience with space-themed tableware including plates, cups, and napkins adorned with stars, moons, and rockets. Add a sprinkle of star-shaped confetti for an extra magical touch.
