Stonehenge fine art papers are 100% cotton, with a smooth, flawless, slightly mottled surface to resemble vellum. They are acid-free, buffered with calcium carbonate to help protect artwork from contaminated environments. Created over 30 years ago, Stonehenge was originally created for a variety of printmaking techniques including etching and silkscreen. Over the decades it has become one of the finest papers for pastel, pencil, charcoal, acrylics and watercolour. • 250gsm weight • 100% cotton fibres • Acid-free • 2 deckle edges • Smooth 'vellum' surface.
