Opaque and translucent

My problem: A good 2 m wide, deep soil bedroom window right next to a busy street and an equally busy sidewalk. My first attempt at preventing others from glancing, was a tightly woven voile Store, where I still constantly had the feeling that one can look from the outside into the room. That's why I now ordered me these curtains. Now I can not see out, but am finally sure and that is more important to me, no one can daily. Translucent curtains are anyway. Only with the rigid Curling I can not make friends really me.
