These panels are white thin plastic.  I was hoping for something more substantial that I could back with rice paper or stained glass to make them into window decor that would allow in light but not be seen through.  The openings are so large that they don't provide any type of privacy.  They attach to one another with thin metal hoops which look like they could lose shape easily.  The holes in the edges also look like they might tear somewhat easily if pressure is put on this screen-like divider. I got them on sale so I will keep them and find a way to use them.
