Grene rugs and blankets were a traditional style of blanket woven by the Saami on warp weighted looms. They were made of hand spun wool. The top edge of the blanket had a braid that was woven using a Saami weaving reed. The weft threads of the braid were the ends of the lengths of warp threads. This braided edge helped to provide the correct sett to the weaving and created a firm and stable border which was then tied to the top beam of the warp weighted loom.
