Decorating your apartment can be a fun undertaking, but if you aren't sure where to begin, it might also turn into a time-consuming (and money-consuming) endeavor. So when you're thinking about adding some style to your existing space, trust the experts to give you a few pointers. Here are three tips from interior design pros that should help you get started.

1. Add mirrors everywhere. Whether your apartment is a series of open, sweeping spaces or it gives off a cozier vibe, hanging a few mirrors will exponentially increase the space—or at least, give that illusion. Search your local thrift stores for mirrors with as much character as the rest of your apartment, and hang them facing windows so that the streaming sunlight bounces off of them.
2. Go ahead; overdo it on throw pillows. Piling on the throw pillows not only makes your couch look more inviting and comfy. It also gives you the opportunity to layer patterns and contrast textures. Double up on throw pillows, placing at least two at either end of your sofa, to add depth and style to your living room. Don't be afraid to mix and match prints and colors when you pick your throw pillows.
3. Repurpose stuff you already have. If you don't have a big budget for your home makeover, don't go out and buy a bunch of new pieces. Instead, survey what's already in your apartment and let your creativity take the reins. Maybe there are some items you could spruce up, like a lackluster end table that just needs a coat of paint, or a weathered dresser that could benefit from some new knobs. Simple switches might make all the difference.
