To make this planter box you have to take equal sized wood shims. Join three together to make the base of the box. For joining purpose you can use a combination of hot glue and a heavy adhesive such as E6000. Then make the sides with two shims each. Cut the shims to fit the two shorter sides of the rectangle box in formation. Then fill the box with tiny planters of herbs or succulents. If you want you can stain the box too or embellish it further with acrylic paint. Hope you will enjoy this easy-peasy project. Happy decorating!
