One of the most important features when decorating is LIGHTING. It does not matter how amazing you think your space is, if it does not have good lighting its just a lost cause. One of the first things that we did when we moved into our loft was swap all almost all of the light switches with dimmer switches. It enables us to have task lighting when we need it and soften the mood when guests are over.
I also love to use lamps or track lighting as an artistic expression. It is one of the easiest ways to combine art with function. Check out a few of my favorites from fellow Etsy artists.
