NOTE: These measurements are exact and they will be used for half square triangles. I prefer to cut mine a little larger and trim them down to the perfect size. If you would like to make yours larger and trim them down, please cut your squares just a tad larger.
Fabric 1 – Cut 1 – 4-1/4″ square. Cut it on the diagonal twice to yield 4 triangles.
Fabric 2 – Cut 1 – 4-1/4″ square. Cut it on the diagonal twice to yield 4 triangles.
Using these triangles, make 4 half square triangles. If necessary, trim these to 2-5/8″.
Step 2: Sew the half square triangle to the appropriate piece from Side Triangle Instructions #2.
Step 3: Sew the other strip to the unit from Side Triangles #1 as shown below.
Step 4: Add the strip with the half square triangle to complete the corner triangles. Make 4.
