*Tucks - a series of tucks sewn on the back, so as to make for perfect pleating when drawn (as pictured in the first blue photo).
*Wooden slats - slats are placed inside the roman, so as to make for perfect pleating, and when let down, the roman is flat on the front, with no visible seams (blackout lined only with slats).
*Let us decide - We consider the width, length, and the fabric that you choose in making the decision on whether to use slats or to make tucks.
