A base member in the form of a platform, box or similar unit may also be provided with a plurality of outwardly extending buttons or projections that preferably are arranged in rows and in different spacial locations on the base. The straps are formed with rounded terminal ends having circular openings therein through which the projections are snapped so that the straps may be frictionally connected to the base at both ends thereof via the projections, thereby spanning a portion of the base. Connecting elements are also utilized to connect the straps at the ends thereof in producing certain shapes and forms.
