I love these curtains.  They are a nice pure white, and have a bit of a sheen to them without being silky.  If you're looking for something that will give a light and airy look to a room, these are perfect.  Since they are advertised as lined and thermal, I expected them to be thicker.  They are actually two very thin layers, which still do let some light through (without being sheer at all).  Not sure how much they do as far as blocking cold/heat, but they do look great.
