This pattern is called Exploding Star... It is in the book Scrap quilting Made Easy. It is made from Half Square triangles. I made this in 2001, after winning a basket of fat quarters the year before at the quilt show.
I remember making all the half square and then having to square them all up before sewing. (fairly new quilter at that time) this is only about 45 inches square... but using larger half square would make it bigger.
LOVE LOVE THE QUILT.
