The quality of these curtains might be 3 stars (at a stretch), but they are not well represented by the pictures that were on Wayfair.

First, regarding the quality: the material is fairly heavy, and I believe that these would be light blocking. BUT... they are 100% polyester, and feel like pretty low quality besides. The valance looks like a bulk product; I don't believe any of the seams or edges were pressed, and the stitching is long, almost a basting stitch.

Secondly, they just aren't what the pictures made them out to be. They're shiny, and I didn't expect that. The hem of these valances are trimmed with a bi-leveled fringe (as seen in my attached pic). The fringe is thin and rather ugly (to my eye), and had I seen it when I was looking on the site, I would not have ordered it. These will be going back.
