PROBLEM TO BE SOLVED: To provide a method for three-way extension and stretch sewing with which torsion of a bias stretchable cloth which is a disadvantage is corrected. SOLUTION: A left bias cloth and a right bias cloth are sewn together. The warp weaving direction is the direction of an arrow and the direction of the arrow is pulled up to forcibly sew the left bias cloth and right bias cloth in the warp cloth. Thereby, the resultant cloth in a three-way extensible state is used in a tightly stretched automotive seat to prepare a three-way automatically stretchable mechanical cloth.
