When designing your own kitchen window treatment, there aren’t any rules about using blinds over curtains (or vice-versa). Instead, many stylish windows feature a combination by pairing Venetian blinds with a fabric valance.
Blinds offer easier control when it comes to light coming through your kitchen window. If your window faces east or west, being able to quickly close a set of blinds might come in handy when blocking out intense sun rays.
If you’re more concerned about looks than functionality, curtains offer far more options in terms of design. Even the sheerest curtains still offer some privacy and light filtration, just not to the extent of a set of blinds.
