Half Square Triangle Tutorial

  There is more than one method to making a half square triangle. This method is useful for making a large quantity of half square triangles in a short amount of time.

  Step 1. After you have your fabric, make sure that it is cut 1 inch larger than your desired finished size. The squares pictured are 4 1/2 inch squares. Our finished product will measure 3 1/2 inch square

    Stack your two contrasting fabrics together, wrong side out.

  Step 2. Use your ruler to draw a diagonal line on the wrong side of the fabric.

  It isn't necessary to draw the quarter inch lines on each side of the center line, but I like the reference lines to sew on.

Step 3. Sew a 1/4 inch seam on each side of the center line. 

Chain sew down each side and clip apart.

  Step 4. Using your ruler again, cut down the center of each square, creating two triangles. 
  Set your seams with iron and press your seam to the darker of your two fabrics.

   Step 5. Use your ruler to trim each half square triangle.
Trim the top and side, rotate, and repeat. The finished unit will measure to be a 3 1/2 inch square.

This piece will be attached to each side of your flying geese units and will be used to complete your Star in a Star Block. You will also use the Half Square Triangle Method to create your Star in a Star Points.
