Decorator magazines, decorating shows, different web-sites, shops, good books with good instructions will help you in this case. You also have to visit model homes. Only one question remains “How to make it”.
It would be great to begin with one room you have seen in magazine or model home. It will become your dream room. This room has to make you feel comfortably in the space. We recommend staying in model home and making some pictures there. When you get at home and go shopping these pictures will help you. You may also take a tape measure and a notebook to make some notes and sketches.
