How to Make the Jagged Edge Quilt Block

Join me again this year as I provide instructions for how to make a different quilt block each month. Eventually, all these blocks will turn into a great quilt! For the month of March, we are making the Jagged Edge Quilt Block in this easy tutorial.  

Jagged Edge Quilt Block in white and navy blue

For a 12 inch finished block (12.5 inch unfinished), you will need to cut the following: 

 Background Color (White)

- 17 of 2 1/2 x 2 1/2 inch squares 

- 10 of 2 x 2 inch squares  

- 2 of 6 1/2 x 2 inch rectangles

- 2 of 9 1/2 x 2 inch rectangles


- 17 of 2 1/2 x 2 1/2 inch squares

 Fabric pieces cut out


Make the half square triangles. 

On the back of the white 2 1/2 inch squares, draw a diagonal line, corner to corner. 

White squares with line drawn on them

Pin a color 2 1/2 inch square to the white square, right sides together.  

Stitch on both sides of the drawn line, a scant 1/4 inch away. This is a great time for chain piecing. 

Chain pieced fabric squares

Cut on the drawn line, and press to the dark side. 

Trim to be 2 inches by 2 inches square each. 

Trimming half square triangles

Layout the half square triangles and the remaining pieces to match the picture.
