Mirrors are great tools to make a small dorm room look bigger, but that doesn’t mean you have to just hang one on the wall. You can use mirrors as artwork in your dorm room, making them focal features, rather than simple accessories. There are tons of creative ways to use mirrors in a dorm, depending on what you are allowed to do with your decorations. If you explore your options fully, you may be able to transform the look of your space. Here are some ideas you may be able to use in the future.
Checkerboard Wall
I was watching an episode of HGTV Design Star last night, and one of the designers made a really cool wall of mirrors that mimicked a checker board. It had a bunch of square tile mirrors on the wall, and they were raised to different depths to give the wall dimension. You could do something like that, or you could literally make a checkerboard pattern out of mirror tiles. Play around with some ideas until you find something that works for you.
Mirror Stripe
You may be able to make your ceilings look higher by putting a vertical strip of mirrors on your wall. If you can find a mirror that is as tall as the wall, great. Otherwise, you may have to get titles or a series of small mirrors to cover the space. Put some molding around the edges to give the mirrors dimension, or paint thin lines around it for the same effect. Just make sure it doesn’t look like something you cheaply threw together, even if you did 
Mirror Mosaic
You could get bits of broken mirror and use them to create a cool mosaic for a wall or a piece of furniture. I have done this several times in the past, and I have found that it is best to do this with other glass tiles. That gives the mosaic dimension, rather than just looking like a broken mirror. You could make a mosaic desk top to write on, or you could make a really cool wall hanging. It’s up to you.
Find a creative way to use mirrors in your dorm room, and you will make the space seem much larger than it is. You don’t have to be a construction worker or an interior designer just to make something cool out of mirrors. As long as you are willing to think outside the box, you should be good to go.
