Purchased These In Dark Brown For My Son'S Room And They Work Great At Blocking Out Any Light. There Are Blinds Over The Main Window With A Large Arched Window That Had No Covering So We Needed Something To Assist With Darkening His Room For Nap/Bedtime And These Did The Trick. They Are A Silky(Ish) Material But Not Shiny So They Don'T Look Too Formal For A Kid'S Room. I Would Definitely Buy These Again.
