Roman shades are seen in almost any design setting these days. There are prevalent in the most contemporary of rooms to traditional and transitional spaces. They are an ideal way to treat a window to offer privacy and light control if needed, while offering a clean and simplistic design.
From solids to patterns, almost any fabric can be used for a roman shade. Even the choice of whether to use lining is an option. No lining can offer a sheer effect which is a new and interesting take on the typical shade.
Adding decorative trim gives the treatment a whole new life. Flat trim is purchased by the yard and can be sewn to the fabric to add detail. A solid fabric can be cut and sewn in the same style as a trim to give the treatment a design.

These can be mounted inside the window frame but typically you see them mounted outside the frame just covering the window trim.
They can also be fabricated into a stationary valance. The woven shade provides the privacy in this bath.
Designs of roman shades are either flat or pleated. Pleated, or sometimes called hobbled, have the pleats remaining in the design even when it is lowered.
A grommet can be added to give an added feature to the treatment. Decorative ribbon or tape can be used as a contrasting detail.
