This is the review I would have liked to have read, so I'm writing it.  I Used one panel a window for a regular size bedroom window..  It comes with two panels. The panel lets light in but the weight is like a cotton bed sheet.  I didn't know if the panels were sheer curtains and they are not.  They are a nice cotton fabric well sewn.  I bought other black (black out) drapes and layer them on top with pull back hooks for easy morning (pull those curtains back) behind the brass tieback bar.
