apartment therapy changing the world, one room at a time

I have two bedroom windows that I need to put shades on. I'm getting rid of cheap mini blinds. I'm contemplating doing something that I saw in one of the small cool contestants last year (I think; southern CA or FL, someplace with a lot of sunl; a studio with a sex and the city-type closet and a room divider at the end of the bed; the owner designed a lot of the furniture herself), where she had two blinds: one to filter out strong sun, and a second set of black out shades. Any ideas of where to start looking for these, keeping price in mind?
