"Everyone needs TLC for "Total Light Control" day and night. That's just what ROCLON delivers with these exceptional high quality blackout liners for drapery applications. Please note that these liners are marked irregular. The irregularities on these pieces are minor. Some have a lock stitch issue which is not noticeable when these liners are put up and does not impair their performance. We hand inspect each liner to insure cleanliness, completeness, and usability.
