Gender Reveal Invitations for a Planetarium Night
The dome is the screen. Here's how to word, time and send gender reveal invitations so guests are seated before the lights go down.

The lights in the dome go down at 20:30. Anyone still in the lobby hears the projector start through the door. Gender reveal invitations for a planetarium have one job: get people into a seat before that moment, because after it there is nothing to see from the corridor.
The room does most of the work. The dome is the screen, the stars are already up there, and all you have to do is write the address, the two times and one line that holds the suspense until the projector starts.
Gender reveal invitations when the dome is the screen
Treat the room as part of the design. Write the cover line, name the exact door, and put the venue where people will actually look for it. A photo of the empty dome does more for the mood than three adjectives about stars.
- Cover line: 'The show starts when you walk in', with the date underneath.
- Full address: planetarium name, dome room, and which door guests should use.
- Cover photo: the empty dome or the projector switched on, shot from the back row.
- Two times side by side: arrival and blackout.
The blackout time runs the night
Split the timetable and say it twice. '20:00, welcome in the lobby' and '20:30, lights out'. Then one line on the threshold scene, where nobody can miss it: 'No entry after 20:30. Come for 20:00.'
Add a question to the RSVP form: 'Are you coming to the projection or only to the toast afterwards?' The answers arrive in the confirmation list inside the invitation, so you know who to expect in the dome and who is coming later for the drinks.
Midnight blue before baby blue
A dark room swallows pale blue. Midnight blue with soft gold accents still reads on a phone in a taxi. Two colours and one metal are enough — a starry gradient competes with the real projection and looks worse on a small screen. Choose the palette, check it in the phone preview, then choose the typeface.

The dome is the only screen you need. The invitation just has to have everyone seated before the lights go down.
One link, and the name can wait
If the name is not decided yet, let the wording carry it: 'Boy or girl, the dome decides the name.' If there are older siblings, a photo of them looking up at the dome beats three sentences explaining the same thing. And when the room or the hour changes, you edit the invitation and the same link shows the new version — nobody gets a second message with corrections. Try the design free first: in trial mode you edit the cover without paying, and buying unlocks every scene. Pick one, write the blackout time, publish.
