Cordless "roll up" is not truly accurate.  Yes, there is no cord, but NO! It is impossible to roll these up without causing damage.  The clips break the reeds (pieces all over the floor while trying to attach the stupid design)... and the cheap clips are far too weak to hold the weight of the heavy rolled portion.  The liklihood for damage to (ie. breaking) the thin threads that hold the entire blind together (by attaching the clips) is also pretty risky.    We now own a couple of pretty blinds that are much too long for the window and cannot be rolled up safely without a cord.  Not an interior designer look at all - it looks like we don't know how to measure or understand proportion.  I'm a professional so it's Just Sad.
