We noticed after our last trip that one of our window shades had fallen off. The screws do not have a backer and were just in the luian wall board so it didn't take much for them to pull out. Has anyone had this happen before? I don't think a toggle will fit because i don't think the wall is deep enough. I considered soaking the wall board with penetrating epoxy and using a bigger screw but im not sure if that would even work. Anyone have a brilliant idea for me to try?
