This shelf is very easy to build, anybody with circular saw and power drill can build it in no time. It don't even need step by step procedures :)
|the 10" X 10 1/2" part should be 9 pcs. and not 8|
I used pocket hole screws and wood glue to attach the members.
Make three of this.
I used 1/4" plywood for the back of the two connecting shelves.
I attached the legs using dowels and corner braces.
Fill the pocket holes, lets dry and sand. Paint.
