So cool. I just love the idea of it, and it makes a fantastic banner. It made me think back to a year when the annual indoor Christmas display at the conservatory at Matthaei Botanical Gardens featured 'living garments' - gowns and tuxes, etc. - made from similar materials. I tried to find some of my photos of them to share. They, like your display, were a 'one off', and never reappeared, alas. It's so much fun to see what creative people can do with plants.
