Lay out the living room. Your list of furniture and accessories is made; how will everything fit?
An interior decorator or designer can work with you to get the look you're after, and even come up with ideas you didn't know you'd love. If you're going the DIY route, start with a simple sketch of the room on paper. Measure the length and width of the room, including any windows or doors. Plain paper and a ruler are all you will need to draw up the room — 1 centimeter on the paper equals 1 foot (or 1 meter) of real space.
Then measure, draw and cut out paper to match all the pieces of furniture you want in the room, new and existing, including rugs. Don't stress about trying to make them look professional; the basic shape is enough to get an idea. Make sure you use the same formula as for the room measurements.
