Claim Text:
1. A projection screen, comprising: a first substrate and a second substrate, wherein each of the first substrate and the second substrate have at least a first seaming edge and a first mounting edge, further wherein the first seaming edge of the first substrate is joined together with the first seaming edge of the second substrate to form a seam; a first mounting patch attached to at least the first substrate, wherein the first mounting patch has at least one strain relief element, wherein the strain relief element reduces strain about a vertical axis, wherein the first mounting patch distributes a mechanical load across at least the first substrate so that the strain lines in the first substrate are optically at or around a just noticeable difference, further wherein the first mounting patch has a first edge that approximately aligns with at least the mounting edge of the first substrate.
