I love these shades. I work nights and could not sleep during the day. I hung blankets over the windows, but the light kept coming through. I was amazed at how easy these were to put up. There is a grid on the fabric that makes it easy to cut straight and no measuring with rulers. No special tools needed, no holes in the walls. All you need is a pair of scissors.
Now I get a good days sleep and alert and ready for the next nights work.
Love them!
