ID-91-4 PATENT A single sheet business form construction printable in an impact or a non-impact printer includes a base sheet of face stock having a front, a back, a top, a bottom, and first and second sides. The base sheet is adapted to receive a first line of weakening in a first desired location extending adjacent and parallel to the first side to define a first tear strip on the base sheet between the first desired location and the first side. The base sheet is adapted to receive a second line of weakening in a second desired location extending adjacent and parallel to the second side to define a second tear strip on the base sheet between the second desired location and the second side. A first transverse line of weakening is intermediate and parallel the top and the bottom and extends between the first and second desired locations. A lateral strip of adhesive is parallel to the first transverse line of weakening between the transverse line of weakening and the bottom. When folded, a mailer with an internal return envelope results.
