Slip this wonderful 2D paper facade over an old bottle or pint glass to create the illusion of a grand vase, then simply flat-pack it again when you’re done.
 
Designed for dried flowers, but if you’re careful, you can fill your chosen hidden vessel with water and fresh flowers (please be aware that this product is not waterproof).
 
Hand-drawn designs by Liberty, taken from art history: Botticelli’s “The Birth of Venus” & Michelangelo’s “David”.   So you can take your pick which one is on display, depending on your mood - or place somewhere that both sides can be seen around the room.
 
This idea came from many many markets hearing "I love this, but I'm flying out to the States and I don't have room" or "ohhh she'd love this, but I have to post it!" in response to my ceramics... and also from being really annoyed at how much space big glass vases take up when they're not in use... so, here is my solution: flat-pack, light-weight, totally suitcase friendly / fits in an A3 postal envelope.
