I will be purchasing 2 inch wood blinds for my entire home. My windows are 5 foot wide, inside of the casing, with a 1.5 inch inside mullion. I wanted to go with two blinds in each casing, but with the mullion so small the two blind panels would not make the window look like two distinguishable units. I am more concerned about aesthetics here....clean lines. I am thinking that without the defined mullion, a single blind would look better then double blinds? Thoughts? Pictures would be great too!
