Gather what you have
Start with supplies already in your cupboard. No paid kit, special machine or account is required for this project.
Let’s make it
Tear a ghost, not a perfect shape
Tear a rounded white-paper shape about as large as your palm. Give it a wavy bottom. Uneven edges suit a ghost very nicely; no template is necessary.
Make it friendly
Glue the shape to the front of the card. Draw two eyes and a smile directly on the paper. Add a tiny drawn bow tie, a book or a teacup to give your ghost a hobby.
Write a greeting that belongs to them
Try 'Boo! I was thinking of you,' 'You are a frightfully good friend,' or 'A little hello from your favorite ghostwriter.' Add one real thing you appreciate about the recipient.
Turn it into a little delivery
Put the card in an envelope and arrange a handoff with the recipient or their household. A grandparent can leave it at a family place setting; a child can give it to a trusted adult. Keep the message kind rather than startling.
Make it a conversation
Invite the recipient to name the ghost, draw its house or write a one-line reply. The fun is in the exchange, not in making a matching set.
Make it your own
For someone who does not celebrate Halloween, turn the same torn shape into a cloud and write 'A little sunshine for your day.'
Keep a little memory
Keep a copy of the greeting or write down the name the recipient gives the ghost.
A note for the grown-up
Adults coordinate delivery. Do not send children to unfamiliar doors or include private contact details on a card intended for public display.
Adapt supplies and participation to the people joining you. Watching, drawing, dictating an answer or passing are all welcome. Time estimates are planning suggestions, not measured setup promises.
