These cards are cleverly designed by Hillesvag, (in Norwegian) showing all of the colors they use for their Solje, Vilje, Sol and TInde yarns, as well as others. The Norsk pelsullgarn, coming from the Grey Sheep, show all of the lovely heathered yarns offered while the other cards (Sol and Vilje) show the various colors offered in wool spun from Lambswool. You will also see samples of the various gauges offered by Hillesvag, including Varde and Blane.
