Treat multiple windows as one by pairing drapes on only the outer edges. If you need privacy or to block the light but do not want spend the money on the amount of fabric it would take to fully open and close, create stationary drapes just one to two widths each. Layer a shade behind the drapes. If the windows are high, consider a motorized shade, which usually come with a remote control or wall switch. Some remotes can operate up to five separate windows.
