Paperstone is an FSC, Smartwood and Rainforest Alliance-certified material made from post-consumer recycled paper and petroleum-free resin. We've seen it used for countertops, but Seattle-based artist Dinah Coops has employed the hard material to mimic European-style slate coasters and tablemats.

Coops silkscreens her two-color designs onto the coasters and placemats, backing them with thick slabs of cork.
