Measure the length, width and edge (the lip) of the wire shelves with a measuring tape.
Once you have the measurements for the shelves, it is time to outline the foam board, then cut the outlines.
Lay the Contact paper over the foam board. Leave atleast 2-3 inches extra of contact paper on each side to wrap around the contact board.
Final step is to put your foam board in closet. Then you can organize and decorate however you like.
