An artwork substrate (504) including a substantially rectangular receiving portion (508) adapted to receive an art medium, and a frame forming element extending from each side of the receiving portion, wherein each frame forming element includes an outer side panel (510, 512, 514, 516) foldably connected to a respective side of the receiving portion, a rear panel (534, 536, 538, 540) foldably connected to the outer side panel, an inner side panel (574, 576, 578, 580) foldably connected to the rear panel and a front panel (590, 592, 594, 596) foldably connected to the inner side panel; wherein the substrate is formed from a single sheet of substrate material, the substrate has a planar configuration and a folded configuration, and when in the folded configuration the outer side panels extend substantially perpendicularly to the receiving portion, the rear panels are arranged parallel to and spaced from the receiving portion, the inner side panels extend from the rear panels towards the receiving portion such that each inner side panel is opposite and substantially parallel to the respective outer side panel, and the front panels are arranged parallel to and adjacent to the receiving panel, whereby each frame forming element forms a rectangular section frame member on one side of the receiving portion; wherein each frame forming element includes one part of a two-part locking mechanism (550 & 539, 552 & 537, 554 & 541, 556 & 535) at each end thereof; and wherein when the frame forming elements are in the folded configuration, adjacent ends of the channels are secured together by the locking mechanism. |
