Top-Down / Bottom-Up
The Top Down / Bottom Up option (also known as a Duo-Fold) is a great choice for those who want to allow in natural light but keep out nosy neighbors. With the ability to lower the top down while at the same raise the bottom up you can lock the shade in any position you like for greater privacy and light control.
All Fabric Roman Shades come standard in the waterfall style which means that there isn't a valance because the fabric rolls off the front of the headrail concealing the shade's operating mechanism. Should you decide to add the Duo-Fold feature you will likely want to add a valance otherwise the controls will be exposed. If you order a valance the fabric will roll off the back of the headrail like most conventional window shades.
