How To Make the Black Diamond Quilt Block

Join me 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 September, we are making the Black Diamond Quilt Block.  

Black Diamond Quilt Block made in blue and white 

It looks complicated but it is actually quite simple.

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

 Color A (Outside Ring) 

     - 12 of 2 x 2 inch squares 

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

Color B (Center Star) 

    - 4 of 2 x 2 inch squares

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

White (Background) 

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

    - 16 of 2 x 2 inch squares

Sew 

First, create the half square triangles (HSTs). On the white 2 1/2 inch squares, draw a line diagonally, corner to corner. Match a white square to a 2 1/2 inch Color A square, right sides together. Stitch 1/4 inch away from the line on both sides.

Sewing half square triangles

Cut on the drawn line. Press open towards the dark side. Trim to 2 inches square.

 

Repeat using the remaining white 2 1/2 inch squares and the 2 1/2 inch Color B squares.

Layout the half square triangles and the 2 inch squares to match the picture and stitch them together in rows. Press. Then stitch the rows together. Press.
