I have the same thing in my kitchen. I'm hoping to layer it w a bamboo woven roman shade it see if it looks richer since those bamboo shades (in my price range) are still see through.
The only thing hard was cutting it so the pattern was straight (since apparently it isn't actually straight on the fabric, which may be why I found it in the discount bin lol).
Otherwise super easy, even for someone like me with no sewing experience. Just measure the size of the window, and cut & hem your fabric into a rectangle based on those dimensions. Then loop the ribbon around, sew it the same place you made the top seam to hold it in place, and you're done.
