These shades seem to be carefully assembled from mostly natural and sustainable parts. The built-in valence and roman-style draw make these much more attractive than cheap roll-up matchstick blinds. They filter light which doesn't provide complete privacy or totally darken rooms, but they're fine for most purposes. One word of warning: the specified size is actual and not nominal, which means that a 25-inch blind is NOT going to work if you try to mount it INSIDE a 25-inch window frame. The good (-ish) news is that it's possible to cut 1/2 inch off one end or the other, but it's not real easy. I recommend these without qualification for outside mount and provisionally for inside mount.
