From page 158 of Urban Eco Chic by Oliver Heath:
There is a good variety of recycled glass vases available, from everyday cylindrical ones to adventurous pieces. But a glass vase does not need to be big to display its eco-credentials. Dutch designer Tord Boontje, with his partner Emma Woofenden, has created a beautiful set of vases made from cut and frosted wine bottles. Manufactured by a Guatemalan cooperative aimed at getting artisans off the street and back into work, they are part of the Design with Conscience Campaign.
Although not very big, they hold a simple stem or a few flowers.
