Abstract
A grooved supporting member for assisting in the construction of a card structure is provided. Specifically, the grooved supporting member provides support for the beginning foundational planar stackable members. The grooved supporting member includes a planar base member, top surface, bottom surface, at least one edge, and at least one groove. Preferably, the groove is cut completely through the planar base member and provides lateral support for a planar stackable member. In the preferred embodiment, the grooved supporting member has four edges and four grooves, thus providing support for four planar stackable members to create the cell of a card structure. The user may employ one or more of the grooved supporting members of the present invention in a card structure. Further disclosed is a kit including a grooved supporting member of the present invention and a plurality of stackable planar members.
