*Slats are usually, but not always used on Romans that have a pattern, so that when the Roman is lowered, you can see the pattern in the fabric unbroken. The slats are slipped inside; you will not be able to see them. Blackout Lining will always be over the slats on the back.
(You may also choose to use slats on Solid Fabrics also.)
*Tucks are a series of tucks sewn on the backside of the roman shade, which allows for easy raising and lowering of the roman. Lining will be your choice usually: Dim-out or Blackout, or none. PLEASE NOTE: We do not recommend that romans with tucks be longer than 54". If any longer, they tend to loose their stability to stay straight. IN THIS CASE, you should choose slats.
