The header for these blinds is pretty. A muted light bronze color that matches the color of the cellular shade beautifully. Also, the measuring procedure was accurate as written on Wayfair’s website—the blinds fit my window frame well for inside mount. I gave 3 stars because while they were fairly easy to install, The instructions read “don’t use hex screws on the back holes of the bracket. Use flat head screws.” Yet ONLY hex screws were included! The shade slides easily both down from the top and up from the bottom however, there should be a magnet on the frame to properly seat the shade when it is fully open . As it is, it sags a little from the top frame. In addition, the description says “white cellular blinds. “ They are not white they are medium gray-bronze. The OUTSIDE is white. Luckily, the color looks good in the room I bought them for.
