Start with paint. A new color can add a new dimension to your kitchen. Blue and green are calming and yellow will make you hungrier. This is one of the cheapest and easiest ways to change your kitchen, and best of all you can do it yourself. And while you’re at it think about a new stain for your kitchen cabinets. A prime and a new color to match with the walls will change the way you cook dinner.
Then choose some new kitchen cabinet knobs. It will be like you have entirely new cabinets, except at a fraction of the price. For your pantry, maybe some new door knob hardware to compliment your new kitchen cabinet knobs. And finally some new switch plates for your lighting. These little details make a big difference in the general perception of your kitchen.
And finally buy a nice large bowl to place fruit in. A big indoor house plant would work well in that corner and some potted herbs for over the kitchen sink and you will be surprised at the different feng shui and the little amount of money it took for a kitchen makeover.
