I also chose my own size for the quilt - maybe the only thing I did the same as Science Fair is the construction method!
The negative space is a khaki chambray from Village Haberdashery in London, which may no longer be in stock. The backing is a Kaffe shot cotton, possibly called Blueberry.
I quilted in straight lines about an inch apart on the negative space, to keep the quilt soft. On each hexagon I quilted six radiating lines, and a circle at the edge. This quilting is not so obvious on the front, but stands out nicely on the back.
Very pleased with the colour scheme on this one! One final summery picture!
