I had issues with the creases that were in the curtains from being folded in the packaging, so I washed them as directed and hung to dry. Insulated panels left white streaks all over the curtains - luckily, that brushed off. But the wrinkles that are now in the curtains are unbelievable. Used a steamer (even though not recommended) to try to make them somewhat presentable in our family room. Love the color, but will never buy insulated curtains again.
