I ordered three panels of these curtains…for a two-pane corner window and third panel for a single, narrow window. Two of the panels were a fairly similar ‘linen’ color. The third was definitely a different shade of linen. I considered ordering more to try to come up with three from the same dye lot but decided the difference in colors wouldn’t be too bad I could use the one with the biggest difference on its own. That aside, I found the light blocking quality to be quite good and the quality of the covering curtain fabric to be good also. Please note, grommet curtains in general do not lay flat against the wall at the edges so you’re always going to get some light ‘seep’ at each side of the curtain panel.
