Line up is unique in that its character shapes include construction elements. The letters are meant to be cut out in sheet metal or sturdy plastic. The incorporated tabs then need to be folded back, providing the anchor points that enable you to attach the letters to horizontal wires between poles or other architectural elements. When suspended, the letters form words and sentences that appear to hover, perfectly still in the air. A version without the tabs is included to facilitate spacing and mapping out the text. This all-lowercase design is suited for longer texts.
