In 1967, in collaboration with BUL Tromsø, work was started to collect background material which was to form the basis for the design of a bunad for the whole of Troms county. This was done in the form of literature, photographs and some old textiles.
In Anna Grostøl's collections of home-woven fabrics, an old sample from Bjarkøy was found, and on this basis the pile fabric was woven. It had a checkered effect of stripes that you couldn't copy, and therefore you chose to make a stack of vertical stripes that were decorated with velvet bands across the bottom. Anna Grostøl's fabric collection is today at Tromsø Museum.
