The nylon rope is a joke for interior install, you will have wrinkles. I found it best to install projector, go to youtube "white screen 24hr" video, and level the projector. Then install screen in proper position. I installed directly to wall with anchors and applied much tension to get all wrinkles out. If not mounting to the wall directly, make a frame box and put moderate tension on the screen. None of these projector screens are going to be wrinkle free, and the supplied ropes would only be good for a wrinkled viewing outside on a clothes line etc. However under tension the screen is great, very happy with it after the additional work. For any remaining wrinkles that persist, I have a heat gun to apply, but I'm not to that point yet. Will buy again for downstairs doing the same method of tensioning.
