       Roof

      Begin with the hidden (inside) side of the Roof facing you. Step 1 shows the back side of the paper with an X-ray view of the front to show the proper position. This model uses “pinch marks” to establish landmarks on the paper. To make a pinch mark, bring the edge or corner to where the arrow indicates, but instead of creasing all the way, press the paper down at one spot, leaving a little mark. Then release the paper.

      1. Bring the left edge to the right and make pinch marks at the top and bottom.

      2. Fold the left and right edges almost to the center; leave a gap of ¼ inch on each side. Use the dotted lines as guides.

      3. Fold and unfold the bottom edge to the top.
