Do these curtains block out light?

No. They are semi-sheer, so they soften and diffuse daylight but do not darken a room. For sleep, pair them with a blackout liner or use them in rooms where morning light is welcome.

How much privacy do they give at night?

In daylight they hide the room from outside. At night, with lights on inside, silhouettes can be visible, so they suit living areas better than ground-floor bedrooms facing a street.

What rod do the grommets fit?

Each panel has eight nickel grommets with a 4-inch head height, sized for rods up to about 1 1/4 inches in diameter. Any standard rod in that range works.

Are they machine washable?

Yes. Wash in cold water, use non-chlorine bleach only if needed, tumble dry low, and iron warm to smooth the wrinkles that set in after washing.

Why does the fabric look brownish?

The linen content gives the weave a natural, slightly brownish tone rather than a flat solid color. If you want a pure solid shade, a fully synthetic panel is a better match.
