# Sudoku Quilt

Hello new Bake Shop friends! My name is Katie, and I blog at Good Golly Ginger. I’m happy to share my first quilt here on the Moda Bake Shop. I created the Sudoku quilt for my Aunt who is a retired math teacher and fellow quilter. Sudoku is a number game, a puzzle in the form of a grid of nine squares that are each subdivided into another grid of nine squares. The rules of the game can be found here. Instead of using numbers for this game of Sudoku, I chose to use traditional quilt blocks to complete my grid. I used Edyta Sitar’s new batik line, Sticks and Stones. This fabric is such a joy to work with. Any quilty math lover is sure to love this quilt.

**Finish The Quilt:**

- I used 108” Stones River Blue (11100 27) for my quilt backing.
- Quilt as desired. I quilted mine in allover free motion feathered flowers.
- There was plenty fabric leftover from the backing that I used for the quilt binding.

The finished quilt measures 70” square.
