Abstract: One embodiment of the invention is an overlay that includes a sheet comprising a first substantially flat surface and a second substantially flat surface opposite the first surface, an image disposed on the first surface, an adhesive disposed on the second surface, and a backing layer adjacent, and removably adhered to, the second surface, wherein the sheet comprises a plurality of substantially rectangular-frame forming channels that correspond with the image. The sheet may optionally include the substantially rectangular-frame forming channels arranged to define a plurality of neck sections disposed along a longitudinal axis. The plurality of neck sections may optionally have a width along the longitudinal axis and a height perpendicular to the longitudinal axis, and the widths become generally larger while moving along the longitudinal axis from a first end of the neck sections to a second end of the neck sections.
