For a dressy look, cut sheer fabric in a half circle and hem the edge. Using a hot glue gun, attach small silk leaves (which can be found at any fabric store) to the hem of the skirt. Drape fabric over a sconce. To finish, repeat the leafy theme by attaching the same leaves to the branches and place in a vase on the shelf.
If one shelf is nice, several can be wonderful! Use wood blocks or accessories from old cabinets and headboards, or any pieces lying about that you find architecturally appealing. Paint them white. Invert the painted pieces and attach shelf. To add interest, trim each shelf differently, using a hot glue gun to add lace edging, teardrop crystals, antique buttons, etc.
Picture Frame Shelf
To use picture frames to make shelves, first screw a thin strip of wood to the wall to create
a supporting ledge for the back of the glass shelf. The picture frames form the front support. To secure the frames, attach them at an angle from the wall by threading picture wire from the back of the frames to the eyebolts secured in the wall. Make sure the shelf is level, then secure the bottom of each from to the wall with drywall screws and begin to embellish.
For glass shelves with a sea theme, use two architectural elements as the bottom glass support. Place glass shelf on top of supports. Two marble-filled jars make the upper shelf support.
