Faux-linen grommet panels with a white blackout backing
These are faux-linen polyester panels with a white blackout lining, sold as a pair of 52 x 84 inch grommet panels, per the listing. The listing claims full blackout; light can still leak around the edges of any curtain, so a wider rod or wraparound rod helps.
Who it's for: Bedrooms where you want blackout without a heavy, shiny fabric look.
Skip if: You need to block light at the sides; add a wraparound rod or liner.
Alternatives with different tradeoffs — not clones of the same pitch.
