My adjustable macrame working device is comprised of a wide base which is preferably self supported on the floor. I have provided an elongated substantially tall, upwardly standing, vertical post which is rigidly and integrally connected to the base. I further provide an elongated, cantilevered lever arm or beam which is adjustably connected substantially horizontal to the post. The end of the beam connected to the post is provided with a manually operable height adjusting means, including a lever action fulcrum portion which secures said beam slidably but non-detachably laterally and exerts frictional holding pressure on opposite sides of the post by gravitational force when the beam is hanging in horizontal position. Rapid selection of the height of the beam is obtained by lifting upwardly on the beam which releases the fulcrum pressure on the post allowing the beam to be slid freely upwardly and downwardly. When the desired location of the beam is reached the beam is lowered and the weight of the beam and the macrame again applies pressure on the post at the fulcrum point frictionally locking the beam in position for working the macrame in the new location.
