Perhaps the kitchen is your bete noir? If it is you can do a lot with some new blinds and lampshades. Try some potted plants on the window ledge this can brighten most kitchens. If the paint-work really is past its prime then you need to decide whether you need a whole new paint job or whether you can get away with touching up the doors and base boards. If your bedroom needs a face-lift then try some new bed covers and toning curtains. Add a few cushions to your bed and you immediately have a more luxurious look.
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.
