We replaced our day nights with Levolor pleated shades from Lowes. These are cut to fit and available in either room darkening (which we got) or light filtering. They look like a very nice day/night shade, but work very easily and no cords are exposed (see Blinds pictures
for some pictures.
I really like how they work -- simply pull the bottom of the shade down to lower and press the button to raise. A couple of other big pluses are their excellent insulation, ease of installation and low cost ($45 for a typical shade). We have replaced all the old day/nights with these and are very pleased with them.
