What decorations do you need for a space party?

You need six core items: a navy-and-black balloon garland, planet and rocket cutouts, star garlands or a star backdrop, an “Out of This World” banner, matching tableware and a cake topper. Lighting is what sells the theme, so add glow sticks or an LED strip.

What colours should a space party be?

Use navy blue and black as the base with silver, gold and white accents. Navy reads as deep space while silver and gold stand in for stars and planets. Avoid pastels, which flatten the look.
