I have the black out cellular and we LOVE them. I have sheers over them to soften the look. Nothing better than sleeping in a dark room. Mine were special order from Lowes.

I have the Hunter DOuglas Architella Black Out 3/4" Cellular Blinds with the retractible cords and the top down/bottom up feature. I love them a lot and now even like the linen color once I put sheers on the sides of them. Before the sheers I was wishing I bought the white color. They are so insulating all year long and help me sleep since I have lamp posts outside my bedroom windows since my room faces the street.

I have blackout cellular shades from Smith & Noble. They work fine - but just to let you know, I ordered a single shade for my pair of 75" windows and outside mounted them. Because of their width I couldn't do the cordless type - the blackout cells are heavy! If I were to do it over again, I'd prefer to do a 2-on-one headrail cellular, but I couldn't get a straight answer from S/N if they could do a cordless 2 on one.

I have a dark green on the interior side - the outside is a neutral off-white. While it's not as super dark as a plastic blackout roller shade is, it does keep the eastern sunrise out of my eyes.

I have Hunter Douglas black-out cellulars in the bedroom, inside mount. In a previous house, I had the outside mount. In both installations, there is/was a bit of light seepage around the edges, noticable only if the sun is directly shining on the window.

The shades are motorized - best thing I ever did!
