Barns-Graham’s ‘Millennium Series’ prints are dominated by the cross shape which appears in all versions of the series. The artist experimented with colours and used a variety of marks and shapes which appear in different configurations throughout the series. Printmaking allowed Barns-Graham to investigate the relationships between colours in new ways. The artist made this series of prints with Carol Robertson and Robertson’s partner Robert Adam at their print studio Graal Press in Midlothian. Barns-Graham worked with them from 1998 until the end of her life and it was her longest and most prolific collaboration with a print studio.
