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.
A great idea for a decoration would also be a wreath. This is an item that you can make when you have a bunch of small driftwood pieces but no idea what to do with them. The wreath is really simple to make. You just need to glue together the driftwood pieces to form a circle. Hot glue is preferable in this case. The wreath would make a nice decoration for the entrance door or for the wall.
