Front of house windows:
It is common to want the front of your home to be as uniform as possible
- just how uniform is up to you. Most people just make sure that the front
products are generally white. If a stained room faces front and you're using
stained shutters or wood blinds, then you'll have to decide if it's acceptable
visually. Most think this is fine.
The more symmetrical your home the more likely the products should be
similar. People often use one product across the front; however, many also
use one for the first floor and another for the second. It's your house,
so whatever you feel is appropriate should be fine.
