How to Make the Windy Night Quilt Block - Technique Tuesday

This year, for the quilt guild I am apart of, I am providing instructions for how to make a different quilt block each month. For the month of July, we learned about the Windy Night Block. This block is originally designed my me!

(This block is also apart of the International Association of Quilters Night Sky Mystery Block of the Month.)

Windy Night Block

This block has a lot of pieces, but when you break it down, it is pretty easy. 

This is a 12 inch finished block size. 


Background (White)               

6 of 5 inch squares                

Light color for zig zags and center (Light Blue)

6 of 5 inch squares

2 of 2 1/2 inch square

Star Background (Teal)

1 of 5 inch square

4 of 2 inch squares

Star Main Color (Dark Blue)       

1 of 5 inch square

2 of 2 1/2 inch squares

For a scrappy look, use different fabrics with the same value.


  1. Using the 2 1/2 inch squares, make 4 half square triangles.  To do this, place a light blue and a dark blue square right sides together. Draw one line diagonally across the light square. Stitch 1/4” away from the line on both sides. Cut on the line, creating two half square triangles. Press to the dark side. Trim to 2 inches square.
  2. Using the 5 inch squares, create 8 half square triangles from each set. Draw 4 lines on the wrong sides of the white squares and the teal square. It should look like the diagram below. Two lines that go corner to corner, a line horizontal in the middle, and a line vertical in the middle.
  3. Match the teal square, right sides together, with the dark blue square. Match the white square, right sides together, with the light blue squares. Sew a scant 1/4 inch away, on both sides of each of the diagonal lines. Cut on all drawn lines. This should give you 8 half square triangles for each set of 5 inch squares. Press to the dark sides. Trim to 2 inches square.
  4. You should now have 60 half square triangle blocks. Along with the 2 inch teal squares, lay them all out in the order shown on the diagram. Sew them together in rows. Press the rows in opposite directions. Then sew the rows together, nesting the seams. Press flat.
