14 Create a movie theater set-up.
If all the space in your basement has been going to waste, why not turn it into your own personal movie theater? All you really need is a trusty popcorn maker, some super-comfortable chairs, and a big screen on your wall to turn your Netflix binge-watches into something way better. These days, you can score a quality projector ($60) for a fraction of what they used to be, allowing you to create what might just become your favorite hangout spot in your entire home.
