This instructable shows how I used an old oak table leaf to construct a simple yet durable wall shelf which is hung using a french cleat. I know there are lots of intructables about how to make a shelf, but I am particularly fond of the french cleat hanging method due to it's simple construction and how much easier it is to hang a shelf.
Some scrap lumber
1/4" wood dowels
wood or hot glue
tape measure or ruler
saw (preferably with a tilting table or blade to allow for angled cuts such as band or table saw)
