This invitation throws a birthday party on paper. A cream matte ground carries bold black geometric lettering that reads like a poster, a casually tilted teal script line, and a scatter of hand-drawn pastel shapes — a pink starburst, a mustard spiral, a cornflower squiggle — in the flat-vector style of modern nursery art. The guest page lives inside that same sticker-sheet world: the invitation sits in a dotted scribble frame with pastel corner dots, detail rows wear a commissioned icon set drawn from the card's own shape vocabulary (starburst, spiral, pin, party hat, squiggle car), and every panel is a hard-edged sticker with a chunky ink shadow that presses down when tapped. A pastel star field drifts behind the page, the countdown ticks in four pastel dials, and the reply panel ends the page on a solid teal sticker button beside a throbbing starburst. Ideal for a 7th birthday, a first birthday, or any children's celebration that wants a modern, editorial-lite look that photographs flat and bright. The page includes a live countdown, an interactive map with directions and an add-to-calendar button, a note from the host, and a simple reply ballot. Hosts can personalise the name, date, venue and reply deadline without touching the design; every detail row and the countdown update automatically.
