A dual adjustable feather jig for simultaneously holding a wood piece firmly against a stationary rip fence and against the top surface of the worktable. The feather jig includes a lower feather board with a 'T' channel bar adjustably mounted on the bottom surface of the lower feather board capable of engaging the 'T' slot formed on a standard worktable. The 'T' channel is adjustably mounted on the lower feather board to allow the lower feather board to move laterally (X direction) over the worktable when the 'T' channel bar is inserted into the 'T' slot. Mounted transversely on the lower feather board is an upper feather board assembly that includes a vertical feather board designed to be extended over a piece of wood stock to hold it down against the worktable. The vertical feather board is connected to a slider arm that slides longitudinally over a riser board securely mounted to the top surface of the lower feather board. Formed on a lateral edge and lower edges of the lower and upper feather boards, respectively, are two sets of diagonally aligned fingers that press against a piece of wood stock against a standard rip fence and against the top surface of the worktable.
