4. I took the enlarged paper panels (remember 2-in squares are to be scaled up to 1-ft squares) and flopped tracing tissue across each paper wall of the panels, taped the tracing paper down, and labeled each panel. Then, starting at the bottom, I ruled 2-ft squares all across and up the entire paper wall, numbering each section from left to right (I worked later with the drawing panels in sections of 2 or 3 panels…easier to handle!) starting at the bottom and ending up at the top. (Note that at the top I made the squares shorter because the measurements were not equal to a full square in height.) I planned for less detail at the top. ¶ VERY IMPORTANT — I had my architect friend Ed Mah do CAD drawings with 2-in wiggle room margins on all tops and sides of each panel. Even in inches there can be slight variations and this would give me extra allowance if I needed it. The last task in this step 4 was doing the detailed drawings on the tracing paper and putting a cut out model (I called her Betty Boop) scaled to my height, 5’ 6”, on the doorway. I took this again to FedEx Office and asked that the assistant run both the tissue drawing taped onto Ed’s CAD panels (entire wall) at high contrast, so both layers would show up in the final paper. I made three copies for extra “insurance” in case I lost, damaged, or needed another set.
