Throw a 26th birthday that looks like the inside of a sticker book. This sticker pop invitation stacks chunky, glossy sticker letters in hot pink, cobalt, lime and sunshine yellow on a warm white sheet, then surrounds them with the cast everyone loves: a classic smiley, a retro cassette, a lightning bolt, a red heart, cat-eye sunglasses and a striped party hat, each with the thick white die-cut border and black outline of a real vinyl sticker. Marker doodles draw themselves in as guests scroll, torn checkerboard corners frame the page, and the number 26th arrives as a giant sticker numeral that wobbles into place. The guest page is built mobile-first, so it reads perfectly on a phone in a group chat and opens up on a laptop with the stickers spilling into the margins. Guests get the essentials at a glance: the date and time, the venue with a live map and one-tap directions, a personal note from the host, a live countdown in four coloured sticker tiles, and a big pink RSVP button that answers Yes, No or Maybe in a single tap. Every detail is editable in minutes: the name, the age, the date, the venue, the host message and the RSVP deadline. Share it by link, text or email and watch the replies land in your dashboard.
