Stringing up stars on the design wall

A dig through the solids box and a bit of fun with my new 60 degree diamond ruler

resulted in four string stars

Here's a larger view, with black diamonds between the stars.

I've figured out how to do the Y seams

but I'm not sure how I get all these diamonds into a rectangle shape.

I'm linking up with design wall Mondays over at Patchwork Times.
