Look at these lovely trivets from Lithuanian online shop Ona. Each is inlaid by hand with juniper, dried flax, rush, chicory, and straw, so no two are exactly alike. The juniper, they say, gives off a subtle, woodsy scent when something hot is laid on it.
They're food safe so you can flip them over to serve cheese or cut vegetables, too. We like the beauty of the natural materials, and somehow we always seem to be one trivet short when dinner time comes, so this set of two looks appealing. $28.50 for the set at Ona.
