It is a combination of the wave and pleated curtain. The fabric is tailored into the wave curtain pattern with the pleated tailoring style but without pleats (the waves are not as obvious as the genuine wave curtain). It uses the same rails as the pleated curtain, as well as the same amount of yard as the pleated curtain. In short, the customer will get the wave-alike curtain with the equipment of the pleated curtain.
