"I wasn't that successful with this. partly my own fault. It was cold weather so the velcro didn't stick that well to the window frame. when I stitched the other half to my blackout material light came through the stitch holes and seemed to escape sideways through the velcro itself. The velcro itself stuck firmly to itself so that was alright. It just didn't work for me so currently looking at stage blackout and other ways of fixing it. not sure how to rate it really."

"makes life easy just stitch one part to the material, the other to stick to the frame in the case of pvc windows for easy placing and removing"
