Are you in a field that allows for a lot of creativity or do you need to be more tailored? What would your visitors expect when they see your office? Would a cornice work as a way to cover the top of the blinds? Is covering the top of the blinds your goal? A cross between tailored and fantasy would be ribbon criss-crossed over velvet or some other rich looking fabric on a cornice. Do you just want to frame the view? Would spliced drapes do anything for your office? By spliced I mean solid fabric at top or bottom or both with a sheer below, above or between? Probably not what the industry calls them, just the word that came to mind.
