Lightening the Look of Dark Wooden Cabinets

Living in a rental apartment with particularly dark wooden cabinets, I have lightened them up by applying small flowered plaques from the dollar store (reproductions of classic art) with adhesive putty which doesn't mar the surface. They can slip occasionally - but are easily re-applied and really make a BIG difference in the kitchen, establishing a flowered theme I continued in the wall decoration, etc.
