My DH believes that there is a shade that can be turned one way for sheer and the opposite way for opaque. I have seen a duo shade that a different shade for each opaque and sheer built into the same header but cannot find anything like what my husband insists exists.

Does anyone know if this type of shade really does exist? If not does anyone use the duo shades and how do you like them? Is it a pain to switch between the sheer and opaque ones?

Thanks!
