Get solar shades for heat and sun control they allow you to keep the view and are pretty affordable too. They roll up on cloudy days if you like. IMO a much better product for this purpose and the bonus of keeping the view.

Sheers are a classic window treatment. You like them, so absolutely use them. Don't be swayed by what the decorating trend of the moment may be.

I dislike sheers and think they are totally dated but you have to live in your house so do what you want.

Change is the basis of design...but some things are timeless...everything relies on what you need and want...sheers are an acceptable choice if you like them ...
