ABSTRACT:
A business form (and related process) includes a web folded medially to form two plies secured one to another about their marginal edges with a third ply secured about three of its four edges to one of the first and second plies forming a return envelope. The edges of the third ply are offset inwardly relative to the edges of the first and second plies. A fourth insert ply is adhesively secured between the first and third plies along only two of its transverse and longitudinal edges. The two edges are substantially aligned with two of the edges of the second ply, leaving two other edges of the fourth ply inwardly offset from the remaining edges of the second ply.
