The boondoggle ruler is effectively a diamond shaped ruler that isn't on a particular angle that we are used to using, so it provides a bit of a challenge to cut if you don't have the actual ruler. It also provides half lines in both directions for doing partials. To design with it, I was able to create a shape in EQ7 using the Variable Point Layout so that it is exactly what the ruler will get you.
My initial concepts had the point of view from the sky looking down, so the camouflage fabrics were the ground i.e. fields of grain.
As I learned more about the tool and EQ provided the download of fabrics to scale, I got a little bit more detailed about the fabric and its placement.
Scale of the fabric motif has a lot to do with the effectiveness of the quilt.
The scale didn't feel good, so I continued to evolve it.
Here it is with a little bit more detail in the plane and a better ground effect choosing different fabrics:
The flyover version, from the ground looking up on a clear sky day, is quite striking so this is my actual entry:
