Well, I bought the curtains solely to shield from the snow in winter, so they haven’t had time to do that yet. I also am still in the “leaving them down for 2 weeks” stage to acclimate, and they don’t roll up smoothly at all – the vinyl wrinkles really badly – and that is a concern. (See attached pictures) I am told I may have to roll them by hand at first with someone puling the cord at the same time, and I live alone, so that complicates matters. And I should not have to do that at all anyway. I also am still waiting for the 3rd “nice” cleat from Cory. So, ask me this question in a few months, and I can give you a better answer… hopefully!
