In 1989, Gro E. Lyngstad’s parents-inlaw established Grinakervev with a wish to help old patterns and techniques of weaving survive. They started with tablecloths and napkins in linen, but soon they were asked to help keep the tradition with ‘busserull shirts’ alive. The busserull shirt, which was traditionally worn by agricultural workers, has been woven mechanically in Hadeland since 1928, when Kari Nielsen designed the fabric. The busserull shirts are today used much more for formal wear and parties – and some even stop by Grinakervev on their way to the cottage to buy a busserull shirt and use it as comfy wear.
