Abstract: The present invention provides a method of constructing an arts and crafts project using a water soluble composition of low density to make a plurality of child-safe articles. The invention is used for forming toys or construction materials for use in playing a game, constructing arts and crafts projects, or used as building blocks. The composition of the articles used in the invented method preferably comprises a matrix principally made from a food starch supplemented with polyalkylene glycol or a derivative thereof. Alternatively, the composition used in the invented method may also comprise a mixture of a grain, a biodegradable binding agent and water. The composition can be extruded in a sheet-like form, with the sheets being cut and bonded together through the application of water to create an art project. By applying water or moisture, the pieces formed by the invented method can be easily bonded together to create the desired article.
