These panels arrived very very wrinkled. But it is possible to dewrinkle them by placing them in a low heat dryer for a few minutes. The fabric is very light. I thought they would be heavier. But that turns out to be a good thing. They block the sunlight very well. And they work in an office environment to keep glare and reflection off of computer screens. Once hung correctly and not wrinkled they actually look pretty good. We bought 20 panels. And we kept all 20 of them. So there weren't any flaws.
