I also love these discount grommet top curtains that draw your eye up and create the illusion of taller ceilings. Essential for apartment living! Adding a sheer curtain will add more interest too (check out Bedding Inn's custom sheer curtain sale!).
Once I decide on my color palette, curtains are usually next to go up. From there, deciding on a focal point and furniture placement, and then the fun stuff...knick knacks!
