There are four fool-proof ways to imbue a cosy ambiance to the home, and it has mostly to do with accessorising! Start with these:
 
1) Add large, plush cushions to the sofa for depth and colour contrast.
 
2) Use rugs and/or throws for some textural interest.
 
3) Use colours – whether with painted walls or furniture/design features in various colours. Although there are warmer colours, cooler colours can do an equally good job in creating a cosy vibe.
 
4) Look for paintings (or many small ones) to place behind the sofa to anchor the scene, or throughout the home.
