Open shelving is a trend that is here to stay. Using floating shelves made of wood or metal to show off your items are popping up in every room. In the kitchen, these shelves can not only show up some of your interesting wares, but used to hold dishes, spices, apothecary jars, plants, etc.
The standard depth of most floating shelves is 12 inches deep and can be 1.5 includes to 3 inches thick being proportional to the length.
Hint: Don’t crowd the shelves with too many items. Leave space between the grouping of items. Bring in color and balance -mix different heights and weights on each shelf.
