Decorate your living room to serve at least two purposes; enjoy yourself and the company of others. The living room is intended to be a place for socialising as well as the sanctuary where you can hide away and recharge your batteries. It's also the place where you can show who you are; what's your style, your colours, interests and affections. In the end, it boils down to making it as comfortable as possible. There is no blueprint - the only given factor is comfort.
