4 Single door curtain Posted by Sonya Clover on 18th Oct 2019 This is a one sided door curtain. There are no tie backs. It’s not part of a pair of curtains. I bought 4 packets as then matched them up to make 2 pairs, for my patio doors and a window each side of my patio doors. They are good quality and were the perfect length. The pairs of these curtains did not have the length I required.
