We have wooden blinds with fabric toppers. We are thinking about finding a replacement for the toppers. We'd like to have a darkening shade or curtain that can be pulled up. Any suggestions?

I was hoping for a fabric shade that looks nice and goes on the outside of the blinds...maybe one that pulls down in a forward motion toward you- the over orientation rather than the under orientation, but I can't find anything.
The photo shows what I'd like in a rolling blind. I am not sure if this photo is a blind or not. (anyway it can't be purchased).
