Choose shimmering metallic accents, such as silver or gold foil, to evoke the brilliance of stars and celestial bodies and seamlessly tie into the broader celestial theme.

2. Venue Selection

Choose a venue with an open night sky view, such as a rooftop, observatory, or outdoor garden. Ideal locations might include a planetarium, a vineyard with expansive sky views, or a countryside retreat far from city lights.

For an indoor night sky-themed wedding, use projection mapping to create a galaxy-inspired ambiance. This technique projects moving images of constellations, stars, or galaxies onto walls and ceilings, immersing guests in the theme. Consider vendors like BlissLights or AtmosFX, which specialize in event projection mapping.

3. Ceremony Decor

Use a crescent moon-shaped backdrop or altar to align with the moon wedding theme. Decorate it with cascading fairy lights, lush greenery, or metallic elements like gold and silver to enhance its celestial charm.
