How to use this prompt

"Blank banner space at the top for a title overlay" is the layout element that makes this a template, not an illustration — without reserved space DALL·E fills the frame and there's no room for event details. "Jack-o-lantern wearing a tiny party hat" is the whimsical detail that signals a costume party, not a horror scene. "Two friendly ghosts holding balloons" is the cute-not-scary convention that broadens the audience. "Festive but not scary mood" is the tonal instruction that keeps the invitation family-friendly. "No dates" prevents the model from adding garbled numerals. The 2:3 ratio is the standard invitation card format.

Variations to try

  • Swap the jack-o-lantern for a black cat in a witch hat for a different party invitation
  • Change the palette to pastel pink and black for a chic adult Halloween party variant
