Step through the cathedral doors into a kingdom made of coloured light. This stained glass unicorn birthday invitation frames a young princess and her unicorn inside an ornate gold gothic arch, every pane rendered in the deep jewel tones of real leaded glass — plum and emerald, ruby and antique gold, lit as though a candle sits behind it. It was designed for the child whose birthday party deserves grandeur rather than balloons: a fantasy princess celebration with the atmosphere of a medieval cathedral at dusk. The guest page carries the same craft as the card. A leaded rose window ignites pane by pane behind the honoree name, wide shafts of coloured cathedral light drift across a candlelit stone interior, and the invitation itself hangs framed as an artifact beneath a hand-drawn tracery crown, tilting gently toward your cursor. Event details sit in lancet-arched glass panels, the countdown ticks inside gothic window frames, and the reply section is sealed with a wax crown that presses itself into the page. Every ornament shares one motif — the pointed arch and the dark leadline that cuts real stained glass — so the whole page reads as authored rather than assembled. Ideal for a 5th birthday, a milestone princess party, a unicorn themed celebration, or any fantasy birthday where the family wants something closer to an heirloom than a novelty. Personalise the honoree name, age, date, venue and reply-by date; guests RSVP directly from the page, add the date to their calendar, and open directions to the venue in one tap.
