Unlined
Recommended for sheers or fabrics that are already 100% blackout.
Choosing the unlined option means the curtain is made with just the face fabric—no added lining. It's lightweight and breathable, but offers minimal light blocking. We recommend this option only if:
● You're ordering sheer curtains
● Your selected fabric already blocks out all light
Unlined curtains are not recommended for standard fabrics, as they offer minimal privacy and may allow light to pass through. If you need more coverage, please consider a lined option.
