Joey Kirkpatrick and Flora Mace are artists who have maintained a collaborative practice since meeting at the Pilchuck Glass Studio in 1979. Kirkpatrick was born in 1952 in Des Moines, Iowa. She received a BFA in drawing from the University of Iowa, Iowa City (1975) and did some graduate work in glass at Iowa State University in Ames before moving to Washington State to attend Pilchuck. Mace was born in 1949 in Exeter, New Hampshire. She received a BS in fine arts from Plymouth State College in Plymouth, New Hampshire (1972) and a MFA in sculpture and glass from the University of Illinois, Champaign-Urbana (1976). She was already working as a teaching assistant at Pilchuck when Kirkpatrick arrived in 1979.

Though much of their work is in blown glass, they also create sculptures using wood and other mixed media. Known for fabricating super-sized versions of familiar objects like fruit or paint brushes, Kirkpatrick and Mace collaborate by dividing the labor according to their individual strengths. Kirkpatrick is often responsible for conceptualizing and drafting up ideas. Mace then takes the drawings and monoprints from her partner and executes them in three dimensions with Kirkpatrick acting as an assistant. Initially met by resistance from gallery owners who balked at seeing a co-signed artwork, the two artists have built an enduring career around their collaboration.

They have mounted exhibitions around the country and are represented within numerous collections including the Metropolitan Museum of Art in New York, and the Seattle Art Museum in Seattle, Washington. They maintain a studio in Seattle and have remained connected to Pilchuck throughout their careers. In 2006, they were interviewed by the Smithsonian for the Archives of American Art, and they were finalists for the Neddy Artist Fellowship in 2009. Kirkpatrick and Mace were elected Fellows of the American Craft Council in 2005.
