• a starting piece, between 0.05 to 0.15 inch in thickness, made of a transparent material, having a squared beginning edge, being at least 3 inches in width, with two equal side of length between 5 and 6 inches, and having an open end of five equally spaced, extended, interlockable coupling fingers on the open end;
• an end cap piece, between 0.05 to 0.15 inch in thickness, made of the transparent material, having a squared ending edge, being at least 3 inches in width, with two equal sides of length between 0.5 and 1.5 inch, and having a minimum of five equally spaced interior couplings to accept and join the interlockable coupling fingers of other pieces;
• at least three straight pieces, each between 0.05 to 0.15 inch in thickness, made of the transparent material, being at least 3 inches in width, each straight piece with two equal sides of length between 6 and 7 inches, and having a minimum of five equally spaced interior couplings on one end, to accept and join the interlockable coupling fingers of other pieces and having a minimum of five equally spaced, extended, interlockable coupling fingers on another end;
• wherein when the starting piece is coupled and capped with the end cap piece or coupled with one or more of the straight piece of the three straight pieces and capped with the end cap piece, a transportable, perfectly flat square or rectangular ruler measuring at least 3 inches in width and one of 6 inches, 12 inches, 18 inches, 24 inches and continuing in 6 inch increments, in length, is created, which can be used for marking, trimming or cutting.
