New 1904 Star Block Calculator

I've just uploaded the 1904 Star Block calculator. It is a fairly intricate block that I made with multiple quantities only, but I think I've broken it down enough for easy assembly. It does use templates and  I have learned to embrace using templates except when my printer is out of ink :)

The 1904 Star block is made with squares, half square triangles, quarter square triangles and peaky and spike blocks. It uses 6 fabrics and in this example I used 3 color groups.

For a 12 inch block, finished pieces sizes are...
Center square = 3 inches
Half square triangles in corners from 3 inch square
Quarter square triangles from 3 by 1½ inch rectangle
Peaky and spike unit is 4¼ inches square
