Home interior decorating covers many aspects of the tasks. A lot depends on how much time you have to spare and what your budget is - whether you just want to spruce up a room or give it a whole new look. It is surprising for instance what new bath mats and towels do for a bathroom. Try sprucing up your room with some new cushions and perhaps a mirror or two. Move the furniture around and add feature wall paper on one wall - make sure that it tones in with the existing color scheme and you will be surprised how much style this can give to a room.
When you first get started on home interior decorating, it is a good idea to have at least some notion of the kind of color scheme you might like. That is not to say that you cant change your mind while you are working out a plan. It is much better to change at this stage than when you already have the paint on the walls.
