Curtains and other fabric-type window treatments have had a resurgence in the past several years, but I advise you to lighten up on any thoughts of heavily styled treatments.
When planning the designs for your window treatments, consider treatments that, when open, expose the entire window, letting the light shine in. A fabric scarf draped over decorative rodding is all that is needed in many cases. Pleated shades can be added for room darkening and privacy.
