I just spent a fortune on wood blinds for our new custom home. They are a very deep red cherry to match all the woodwork. Question is -are you suppose to put curtains over them?

It is really up to you. We did the same when we bought this home almost 6 years ago, and although I made window treatments for some of the rooms, the MBR went until last winter without anything other than the blinds. Then I decided I wanted just another layer for decorative purposes. I've seen some rooms that look complete with just blinds.

The house we bought 2.5 years ago, has gorgeous, custom, wooden blinds on every window...

...because they are dark wood, I only put swags at the top of the ones in the Great Room

I did nothing to the ones in the kitchen for the same reason (didn't want to make the window any darker)

I did do lightweight drapes on the Bedroom windows however because I like it totally dark for sleeping.

Just use a fabric valance.
