Abstract: A device for making decorative ribbon bows comprises an adjustable quadrilateral frame structure formed of four individual elongated planar members which are pivotally attached to one another. First and second elongated planar members form opposite sides of the quadrilateral frame structure, each formed with an elongated slot extending longitudinally through the member. A third elongated planar member contains pivotal connections at opposite ends thereof for pivotally attaching to the elongated slots of the first and second elongated planar members. A fourth elongated planar member contains pivotal connections at opposite ends thereof for attaching to said first and second elongated planar members at points separate from said slots. The third and fourth elongated planar members further include arrays of spaced upstanding rod elements for passage of ribbon material between them.
