Digital invitation mistakes for a Halloween kids' party

It's the Thursday before Halloween. There's a carved pumpkin by the front door, a box of fairy lights on the kitchen table and a group chat where someone has just typed 'so what time, then?' You planned a small party in the garage for kids of three to six. What you have is forty messages and no clear answer. Most of the mistakes with a Halloween digital invitation for a children's party aren't design problems. They're a time, a link and one adult. You can pick a design from the catalogue, add your own words and photos, and send it today.

Here are the three that fill a garage with the wrong people at the wrong hour, plus what the page itself should say so nobody has to ask you anything on the night.

Digital invitation mistake 1: the wrong time for a Halloween kids' party

A party for three-to-six-year-olds lives or dies between 5:30 and 6:00 in the afternoon. Put 7:30 pm on the page and families turn up with half-asleep small people, while you're lighting candles that were meant to be lit an hour earlier. Write a start and an end. In a garage strung with dark fabric, parents need to know when to collect, not only when to walk in.

• Spell out both hours on the front of the page: '5:30 to 7:00 pm', not just a start time.
• A three-year-old at 7:30 pm is a tired three-year-old. Eight of them in a garage at 8 pm is a different party from the one you planned.
• Torn between two slots? Publish one and watch the replies. Change the time later and the link stays the same, so nothing needs sending again.
• Be honest about the end. If the sweets come out at 6:45, say 6:45, so the adults collecting at 7 aren't standing outside a dark door.

How to create digital invitations that actually fill the garage

Parents of a three-to-six-year-old don't improvise a Saturday. They need ten days to a fortnight to fit the afternoon around naps, find the costume and work out who drives whom. Send the link on a Tuesday afternoon, not a Friday at nine at night. A short message with the link and one photo of the pumpkin table gets read. A three-minute voice note doesn't.

Ask for an answer with four days to spare. The Friday before should be for counting small chairs and plastic cups, not chasing people. Because the replies arrive inside the invitation itself, in a list, you're not scrolling back through a chat to work out who's coming.

The invitation isn't the message you send. It's the page that stays right while people answer.

The adult nobody told: the real headcount in the garage

Eight small chairs fit in a garage hung with dark fabric and lanterns. Adults standing up are a different sum, and that's where the doorway gets crowded. Put it in the text: 'each child comes with one adult'. Siblings are the next surprise — invite a three-year-old and the family often arrives with the six-year-old too, so say whether brothers and sisters are welcome. You can also add your own RSVP question, something like 'how many adults are coming with you?', and the answers land in the same list as everyone else's. If the pumpkin table is already in your head, don't announce it with a message at eleven at night. Choose a design, write the time, the address, the photo of the lanterns and the line about one adult per child, then send the link. The page is yours for 29,99 EUR, one payment, and if the hour or the place changes, guests see the new version at the same link without you resending anything.
