It seems a shame to leave a windowsill bare and not utilise its potential as an extra space for decorative and storage purposes. And while that might be true in some cases, there are certain things you should never put on a windowsill as it could pose a safety hazard or cause damage to those very objects.
Placing decorative objects on your windowsill can sometimes be a beautiful way to dress a window, or use that extra space in a practical way for storage. But making it full and cluttered is never a good idea as it could interfere with the functionality of your window or obstruct a potential escape route in case of emergency.
