Shelf brackets for grid wall, great for craft fair displays.  I wanted to be able to make the shelves as long or short as I needed, so I created brackets to hold pieces of wood.  I have included two brackets:

Small Bracket:  Holds a stock piece of 1"x 4" wood trim found at any big hardware store cut to preferred shelf length.

Large Bracket:  Holds a piece of ¼" plywood.  I would buy a sheet of plywood and cut out pieces 7" wide, then cut to preferred shelf length.
