Window Treatment Hardware

I have a window (or a set of windows) in my family room which occupies an entire wall. I do not have exact measurements, but it has nearly 84 inches tall and 108 cm long. I want curtains / curtains / window treatments (they are called) did. I know that a major cost factor is the type of fabric I choose the better hardware, but can someone give me a price range so I can start budgeting? Just to make it easy, let's say I select a fabric that is $ 20 a yard.

The best thing for you would be:
# 1 exact measurements of your window.
# 2 search company / designer who is custome window treatments

They will then be able to help you choose what is best. They can price and you can contact them as soon as you have money.
