Centerpiece \Cen"ter*piece`\, Centrepiece \Cen"tre*piece`\, n.
An ornament to be placed in the center, as of a table,
ceiling, atc.; a central article or figure.
certainly not an ornament, but simply the leftovers of a bunch of flowers put into a little pot and decorated with some moss. perfect if you only got a few (almost dying...) flowers. add a little tag with a name on it and your centre-piece or place card is done. put on a plate or into some invy and your table is set.
