This is the center for my OZ quilt, measuring 60 inches square. I forgot to mention when completed, this will contain 712 - 2 1/2 inch squares all sewed together individually (not sewn in strips, then cut up) I wanted the square placement to be sort of random.
Scarecrow: "The sum of the square roots of any two sides of an isosceles triangle is equal to the square root of the remaining side." I bet he was a quilter! 12 of 25 blocks for the center.
I cut most of the strips from the Oz jelly rolls into 2 1/2 inch squares. I sewed them together randomly, as well as alternating blocks of squares and triangles.
I saw this quilt by Sarah Fielke in the book Material Obsession Two, it's a wonderful scrappy quilt, mine will be from one fabric line.
