One of the first steps in making a space feel like home is hanging photos and art. You could do this with frames from the dollar store and mix in a decorative mirror or other matching, wall-hanging items. I want to do this with black frames and black and white photos, Playbills, etc.
Dividers in the deep space above the oven or refrigerator are an efficient way to storage your platters, cookie sheets, cutting boards, bakeware, etc. Add shelves above the dividers to maximize storage in taller cabinets.
