Hopefully my last window treatment question.

So, my living room has a large bay window, and one regular sized window on another wall.

I bought silk dupioni drapes and voile sheers with a cast iron double rod for the bay window (the window is odd and it was my only option...you cannot mount shades/blinds anywhere).

For the regular window (couch is centered in front of it)....I can either buy the matching silk shade from PB (but wow is it $$$ for a shade)...which would be in the same color and match...

OR....would it be okay to do something different, such as white wood blinds (white trim) or a white roman shade? Are those too informal, considering the bay treatments are somewhat fancier?

OR....should I also do the curtains and sheers......

Why is this so hard?

I would get the matching shade from Pottery Barn.
