We put together a selection of vases that look as good (if not better) empty than when filled with flowers and/or greener. Note: the newspaper shows more vases than are shown online, but online you’ll find pieces by Amber Cowan, Tung Chiang of Heath Ceramics, Esque Studio, Tracey Glover, BZippy, Wyatt Little, Mica DeMarquez, and Eric Astoul.
