*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.
This Cord Lock System works like a venetian blind, locking roman in place, but remember you will still have a cord to contend with, every time you draw the shade, which you will wrap around a cleat. This SYSTEM cost $50.00 extra, which will be collected at shipping with your balance.
THIS SYSTEM IS NOT NECESSARY, IT IS JUST A PERSONAL PREFERENCE.
