Hannah Ryggen used wool from her own sheep which she carded, spun, and dyed with natural dyes made from locally foraged plants, lichens, and bark. Ryggen did not work from sketches or plans, but created her compositions directly on the loom with a variety of weaving techniques, resulting in simplified figures set against striking organic and geometric patterns. This is "Ja, vi elsker" (1950, Trondheim), a title taken from the opening words of the Norwegian national anthem.
