Paired Half Square Triangle Tutorial

By Laura Loewen

Making paired half-square triangles (HST) is simple and easy using two squares cut 1” larger than your finished HST. Our example photo shows a 3” finished HST. We start with 4” cut squares and trim our HST to 3.5” unfinished.

Step 1

Begin with (2) squares the same size, one of each of two different fabrics.

Step 2

Line up squares right sides together. Draw one diagonal line from corner to corner.

Step 3

Sew ¼” on either side of the drawn line. (pictured are extra squares cut and ready to be sewn for step 2 and one square unit sewn and ready for cutting as in step 4 )

Step 4

Cut along drawn diagonal line.

Step 5

Press open and trim to unfinished size, ½” bigger than finished size. Take care to line up diagonals at corners.
