Founded in 1975 by Elaine and Donna Koretsky, Carriage House Paper is a Brooklyn hand-papermaking studio that makes handmade paper and supplies papermakers with the equipment and materials to make their own. Its fully equipped facility also hosts small workshops, private instruction, studio rentals, and artist collaborations. The company’s work is closely tied to the Koretskys’ international research into traditional papermaking, including the International Paper Museum directed by Donna.
