Double-layer roman shade

Abstract

A roman shade includes a headrail, a first shade cloth mounted on the headrail, and a second shade cloth mounted on the headrail and having a light permeability different from that of the first shade cloth. Thus, the first shade cloth and the second shade cloth have different light permeability, so that the first shade cloth and the second shade cloth are used individually or co-operate with each other to provide different shading effects, thereby changing the indoor viewing effects so as to satisfy the user's different requirements.
