Norwegian designer Kristine Bjaadal showed her Underfull Table Cloth at the 2010 Stockholm Furniture Fair and since then it has been getting quite a bit of press. This special table cloth features a simple damask pattern, yet hides a secret. When colored liquid — like red wine — is spilled on its surface, it reveals a hidden butterfly pattern. Still a concept, Kristine is working on getting these into production.
