6 ̋ Flying Swallows block
Sum of parts: 3.414



  1. 6 ̋ ÷ 3.414 (sum of parts) = 1.7574 = 13/4 ̋, which is
    the size of the A square and B triangle.

  2. To find the size of the smaller C triangle and D dia-
    mond situated along one edge of the A square, you first
    need to determine the sum of the parts along that edge.
    There are two C triangles along one edge; these two tri-
    angles are the same, although they each have a different
    side touching the square. Therefore, the assigned value
    is 1 for the short side and 1.414 for the long side, and
    the sum of the parts is 2.414. If you divide the size of
    the square (1.7574) by the sum of the parts (2.414), the
    result is the size of the C triangle on its short sides and
    the size of all 4 sides of the D diamond.


1.7574 ÷ 2.414 = 0.7280 = 7/ 10 ̋

In this case, the A square and B triangle would be
drawn on 8-to-the-inch graph paper, whereas shapes C
and D would be drawn on 10-to-the-inch graph paper.

6 ̋ Rolling Star block


  1. To determine the size of the A corner triangle, divide
    the block size by the sum of the parts along the edge.
    Sum of parts: 3.414

  2. 6 ̋ ÷ 3.414 (sum of parts) = 1.7574 = 13/4 ̋, which is
    the size of the A triangle.

  3. To determine the size of the B square and C dia-
    mond, you need to determine the sum of the parts inside
    the block.
    Sum of parts: 4.828

  4. 6 ̋ ÷ 4.828 (sum of parts) = 1.2427 = 11/4 ̋ for the B
    square and C diamond.
