Rushnyky: Sacred Ukrainian Textiles celebrates and explores Ukrainian culture through one of its most ancient and valued traditions.
A rushnyk is a long, rectangular cloth, typically made from linen or hemp, which is woven in one solid piece and sometimes adorned with bright, intricate patterns. They are traditionally made by women, who start learning to spin, weave, and embroider the cloths at a very young age. Today most rushnyky are machine made using modern materials, and can be purchased in retail establishments.
