Unroll the wool rug completely onto a flat surface. Make sure that the floor area is free of other objects or furniture.
Flip the rug upside down so that the curled edges are facing downward.
Walk around the edges of the rug, covering the entire perimeter of the rug. Continue walking on top of the rug for about 10 minutes.
Place heavy, hardback books around the perimeter of the rug. Allow the books to remain in place for about 6 hours.
Take off the books and flip the rug right side up again. The rug will be flattened.
