You are selecting added features of the drapery.
Lined:Panels will be made using the face fabric and then lined in a cotton fabric.
Lined & Interlined:Panels will be made using the face fabric, lined with a cotton fabric with a flannel lining in between. This will provide optimal insulation and some room darkening qualities. If using silk we always recommend using this option as it helps protect the silk and give the panels great body.
Blackout Lining:Panels will be made using the face fabric and then lined with a blackout fabric. This option is great for a bedroom or media room. Note that using blackout lining will give the drapery a stiffer hand. Using blackout lining is not recommended if you want a puddled look.
