Coasters are hand spun from .040 copper, which lets us design our own shape and size. Then they are enameled with unleaded enamels, The edges are stoned, buffed and coated with bees wax. When all other work is completed we install a cork bottom, to protect your woodwork, and to prevent condensation from cold beverages from marking your woodwork. All designs and images are original work, and as such are hard to reproduce exactly. Should you need additional work it would be best to order them as a set, and they will match in color much closer.
