Mirrors can be the perfect option when wanting to make a space appear bigger. This is due to an optical depth illusion provoked by the reflection of the light and the elements in the room. Consider the role the mirror will play in its designated space. Will it serve as a decorative element, or will it have a more practical use.
There are infinite shapes and sizes and each one will be suited to one situation or another. You can place them on top of draws, dressers and even fireplaces or if you are more daring and original you can hang them on the wall.
