So named because of the diamond shapes that showed up between the woven diamonds.
This chart is in the Diagrams section, but I think it deserves its own post as well. I left lots of room in the individual blocks for notes or other marks.
Here’s an example of how to use it. This layout was drawn directly onto graph paper and inspired me to make the chart so I wouldn’t have to draw lines for blocks every time I wanted to plan a project.
This pattern can either be a cross shape or a box divided by a fancy plus mark (see caption of weaving diagram).
