Traditional techniques and knowledge are combined with contemporary variations at the Netherlands Open Air Museum. Practice Held in Common participants Takahiro Hasegawa and Anna Wetzel worked closely with groundskeeper Michaèl Brandt and colleagues to care for the flax field, supported by cultivation supervisor Karlijn Bokhorst and WUR masters student Talis Bosma. During the season they together learned about flax cultivation and applied hands-on methods involved in small-scale crop care. For volunteers and visitors to the museum, their activities created awareness of the Dutch cultural heritage of flax production and the inherent connection between agriculture and textiles.
