The whole screen is the back of a kraft four-flap envelope with white-ink pampas, sealed in gold wax: tap it and the seal cracks, the gold rings hop out, the four flaps swing open towards you and your names are written out in handwriting. Torn-edge handmade paper, prints taped with washi, venues as stamped postcards, details hanging on kraft tags, and the gold rings travelling with the guest down the page.
