Abstract: A building block of any geometrical shape having fabric fasteners secured thereto for releasably coupling the block to another block. Each block includes a hollow geometrical shape with hook and loop material alternatingly positioned at opposed edges of the shape to facilitate securement of the block to another similarly constructed block. An alternate embodiment of the present invention includes blocks having either hook material or loop material exclusively with an indicator with each type of material present on the block. A further alternate embodiment provides a separation assembly positioned within the block and operable to facilitate a separation of attached blocks.
