Lace-making dates back to the Renaissance. Lace was used not only to protect fabric edges from fraying, but also for decorative purposes. Brisk demand turned lace-making in Salzburg into an industry of trans-regional importance which developed a style entirely of its own. At the height of its popularity between 1600 and 1800, bobbin lace was an important source of income for many families. Following near-oblivion, the craft was rediscovered in the mid-20th century and has since been taught and handed down in special courses.
