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.
