Cabinets in the kitchen are for storage but kitchen shelving has other purpose and that is to display those plates and dishes that are most frequently used. This is for hassle-free pick and return. You may use the shelves for placing pickle jars, blender, juicer, spice bottles, little ornate etc. Cups that are used ten times a day for tea and coffee are also best hanged on little hooks on the shelves after being washed.
Kitchen shelves are always made on the upper part of the counter. The lower part is for cabinets with doors where you store the less frequently used items. The shelves must be practical. Not very wide shelves are preferred because you need to put only a single line of things; easy to pick and easy to arrange! Moreover, shelves must not be very high that you need to drag a little stool in order to pick some jars from the top shelf. Their practicality depends on the fact that they are your height!
If you are facing some trouble in working in the kitchen and fixing some shelves can make your work easier, look for the possible options. Is the place enough wide on the wall that you fix shelves on it? What sort of shelves you need? The design choice is yours and as far as the design is practical for your needs, you can pick it for your kitchen. Solid wood shelves are a good option as you can paint them whenever you think of revamping your kitchen
