Hang a Mirror
If you don't want to buy an expensive painting or print to hang on your wall, buy a mirror to brighten up your living room. Not only are mirrors a stylish and inexpensive way to liven your living space, but they also can make a small space look larger by creating a sense of depth in a room. The nice thing about mirrors is that you can buy a used one at a thrift store or yard sale, and if the frame is banged up, just paint it.
Remember to hang your mirror in a spot where it reflects something attractive within your living space, like your baby grand piano or your heirloom armoire.
