For rough cut, the quantity ordered is the square foot area of the piece cut. This piece will not be perfect square. The natural shape of the hide and previous cuts will determine the end shape. The piece will be the area ordered though. When ordering for a specific project, we recommend ordering at least 20% extra due to the irregular shaping of cuts.
