Deciding Whether or Not to Purchase Window Valances

I have got some curtains for some of the windows in my home. I am trying to figure out what to do for the others. Someone suggested that I might just want to get some nice blinds and then use window valances, but I am not sure what I think about that. I do like the idea of cafe shutters with valances, but that might be a bit more than I can afford. I will have to look into the cost of these items to see if it is feasible, or if I should just wait a bit until I have more money to spend on it.
