How to decorate your living room with cushions
There is no hard and fast rule about how to display cushions on your sofa but there are a few things that you can do to maximise their effect. Firstly, if you are trying to achieve a very traditional looking room, then you want to go for the classic one:one (matching cushions at each end) or two:two (same thing). This can be an excellent way to achieve a classic or traditional looking living room.
If you want a more modern look, then you have some freedom to mix things up a bit. There really isn’t any rules when it comes to the arrangement of cushions on a sofa for a modern or eclectic look. I’ve seen settings with one large cushion on a two seater and it looked fabulous! I’ve also seen a sofa stacked so full with cushions that there was barely anywhere to sit, but, it looked amazing too. However, unless you are confident about your styling, it might be safe to stick with an average number of cushions 3-5 and have fun with your arrangement. If you have 4 squares and a rectangle try putting the squares at either end and the rectangle in the middle. If you have 5 squares then maybe try the 3:2 arrangement with two down one end and three down the other.
Keep in mind the colours of the cushions when you are placing them on your sofa. If you have one cushion with 2 or 3 or your colour palette in it then try to surround that with the other colours as this will help to pull them all together. The most important thing to remember through all this is to have fun! Try a new arrangement and leave it there for a few days while you see if you like it and then mix it up again until you find one that you love.
