How to transfer pattern and hand cut the pieces
Using page 1 as a guide, draw the pattern pieces onto a large (12" square) piece of black or dark grey card stock. I included the 1/4" grid squares to make the pieces easier to measure. (Construction steps shown with white template rather than black paper for better visibility.)
Light yellow portions indicate places that will be glued. The markings "3g" and "4g" label exactly where pieces 3 and 4 will be glued onto other pieces.
Cut on black lines, removing the solid black cut-outs on pieces 1 and 2.
Score red and green lines. Mountain fold green lines, valley fold red lines.
