ABSTRACT:
An activity toy with which a child may create needle craft like textured designs using plastic or amorphous solid substances. In order to simulate the strands or nubs that create the textured design in neddle crafts a stand supported on a surface holds a screen having mesh spaces extending between the opposed sides of the screen. The stands hold the screen spaced from the surface with one side of the screen facing the child. An extruder for the plastic substance is positioned adjacent the side of the screen away from the child and moved under the screen to force the substance through the mesh spaces to create the needle craft like texture. The extrusion opening is a larger than the mesh spaces so that a mat or backing retains the textured design on the screen. To facilitate the creation of aesthetically pleasing designs, preprinted patterns or outlines are provided on the screen.
