How to Make The Four Corners Quilt Block - Free Tutorial

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 Four Corners Quilt Block.  

Four Corners Quilt Block in Teal, Navy, and White

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

Cut

Light Color (Teal)

- 3 of 5 1/2 x 5 1/2 inch squares 

Dark Color (Navy)

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

White 

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

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

- 3 of 5 1/2 x 5 1/2 inch squares 

Pieces cut out and ready to be sewn together

Sew

Start by making the Quarter Square Triangles (QST). On the white 5 1/2 inch squares, draw a line diagonally, corner to corner.

Match a white square to a light color square of the same size, right sides together. Stitch 1/4 inch away from the line on both sides.

Lines stitched

Cut on the drawn line. Press open towards the dark side. You now have 6 Half Square Triangles (HST.)

Draw a line on the wrong side of the HST, perpendicular to the seam, corner to corner.

Right sides together, match two HSTs together, alternating colors. I.e a teal triangle is matched up with a white triangle.

Stitch 1/4 inch away from the line on both sides.

Lines sewn

Cut on the drawn line. Press. Trim to 4 1/2 inches square.  You will have one extra QST.

Using the remaining pieces, sew a white square to a dark colored square. Press.
