You simply sew strips together, cut them with a 45 degree angle ruler, use the ruler to trim them, and sew the star points together as shown into squares, sew the squares together, and trim again.
My blocks are a work in progress and the quilt won't be completed for a while. I am using a variety of scraps from a few different fabric lines by Bonnie & Camille. I want to add some pieces from their new line "Miss Kate" coming out in August -- it will be a bit "scrappy" which I love!
The blocks will be sewn together with sashing pieces and posts in between them. The ruler has very clear instructions for stars in a variety of sizes, and also includes a free pattern. Below is an example of the free pattern and various size stars.
I'd better get back to sewing now ... lots to do and not enough time!
