A blank sheet of foldable material having a plurality of laterally spaced parallel fold lines dividing the sheet into five consecutive panels to allow for folding of the panels into overlapping engagement. A first leg formed from folding panels two and three so that the top side of panel two is placed in face-to-face contact with the top side of panel three. A second leg intersecting the first leg formed from folding panels one, four, and five so that the top side of panel one is placed in face-to-face contact with the top side of panel four, and the top side of panel five is placed in face-to-face contact with the bottom side of panel one. An adhesive placed between panels two and three, panels one and four, and panels one and five for securing the panels to maintain the legs in a fixed folded arrangement with each other.
