Digital invitation: Halloween bats in a museum

The museum shuts at six. By half seven you are inside with a box of paper bats and a roll of fake cobweb, and the group chat still cannot agree whether the party starts at eight or nine. This is where a digital invitation earns its keep: one page with the room, the hour and the photo of four friends in rubber wings for your Halloween party in a museum, plus a link you can send tonight. Pick a design from the catalogue, fill in the fields and publish.

What follows is what goes on that page: the cover, the wings, the exact minute the lights go out. And the parts you will almost certainly need to change after you have sent it.

How to create digital Halloween invitations for a museum night

Start with the cover. A vertical photo of the museum facade at 20:00, one window lit, the event label sitting above it. Mark it as the cover photo and the frame fits it without odd crops. Inside, the scenes run in order — The Turnstile, The Bat Room, Blackout at Eleven — chained the same way the collection chains its own scenes. Every text has its own field: label, names, date, line and venue, each with a character counter, so the room name does not swallow the whole line.

• A vertical photo of the museum facade after dark, with a single window lit.
• The exact blackout hour and the time you leave — parents included.
• The floor or room where the route starts, written the same way as on the museum plan.
• The dress code in one line: all black and homemade bat wings.

Bat wings on the cover: pick six photos, then swap one

You can upload up to six of your own photos: the empty room with the cases dark, the corridor with cotton cobwebs, the four of them in rubber wings, the sign taped to the door. Each one settles into its frame on its own. Mark the one you want on the cover now and replace it later, when you have the shot of the whole group in costume. The link stays the same.

Add music while you are there. A fairground organ that swells just as the blackout hour appears on screen does more work than a paragraph of description.

The door creaks, the lights go out, and nobody has to ask you what time it starts.

The blackout hour can move, the RSVP stays in one list

If the museum confirms 21:30 instead of 21:00, you change the hour, the map and the line of text, and guests see the new version when they open the same link. Nothing gets re-sent, nothing gets reprinted. Confirmations land inside the invitation, in one ordered list, so you stop counting 'I'm in' between forty pumpkin stickers. Set your own RSVP questions: whether parents come in, whether they stay for the last dance, who brings their own wings. Guests open it in any browser, with no app and no download.

Paper for the two people who will keep it

Somebody's grandmother will want something to hold. The sensible split is a link for everyone and two printed copies for the people who will actually keep them. The invitation itself stays digital — it is a web page, not a PDF — but a screenshot of the cover does the job on a fridge door.

Before the museum door creaks open, decide how the invitation is going to sound. Build your digital invitation for Halloween tonight, drop the link in the group chat and leave a QR by the door for whoever arrives with 4% battery.
