One of the more basic woodworking joints is the half-lap joint. A half-lap joint is where one half of the thickness of the connecting surfaces of two pieces of stock is cut out, and the two boards are then attached to one another with glue and screws. As displayed in the graphic on this page (for illustration purposes, one piece of stock is shown in green and the other in blue), when the half-lap joint is properly formed, it should add no thickness to the adjoined boards.
There are a number of cases where a half lap joint is perfect for two pieces of wood. Learn when to use Half-Lap Joints, and which of your woodworking tools are best suited to properly and safely cut the joints.
