I probably spent years trying to find blinds that wouldn't break my bank.  I opted for one large 71" width by 72" length for four windows versus two in each window. Getting the larger blinds was a lot more cost effective.  The delivery was sooner then expected  and after making a quick trip to Lowes to pick up some metal screws (only wood screws were included) and a drill bit, it took me approximately two hours to install all four blinds by myself.  The ease of rising and lower and the light that filters in even with the blinds down, makes me very happy. I plan to purchase additional blinds for the rest of the windows.
