Curtains cover up your windows. Simple as that. If you want to make sure no one can see what you're up to, you can just draw them across and carry on with your sordid activities. Then when you're finished, you can open them right back up again to let in the glorious sunlight. It's a simple solution to the problem of privacy, and you can really go crazy with curtains too. They come in all colours and sizes, different patterns, pleats, even different ways to tie them back. You can customise your curtains to suit your home, and deploy them whenever is necessary. Curtains are a fantastic addition to any window, but everybody knows that. Curtains are awesome.
