Today we will make the setting triangles and corner triangles.
Using Fabric 4, cut 1 – 9-3/4″ strip. Cut it into 3 – 9-3/4″ squares. Cut those on the diagonal twice to yield 12 triangles. Ten of these will be used and 2 will be leftover. We will be making 10 side triangles.
Using Fabric 1 – Cut 7 – 3-1/2″ strips. Sew a strip to one side as shown. Trim the angle.
Sew another strip on top. Be sure there is sufficient length to be able to trim the edge at the 45º angle.
Using Fabric 4, cut 2 – 5-1/8″ squares. You should be able to get these from the leftovers from the above strip. Cut those on the diagonal once to yield 4 triangles. Using Fabric 1, Cut 2 – 3-1/2″ strips.
Leaving about a 4″ tail on either end, sew the Fabric 1 strip to the Fabric 4 triangle. Trim the edges using a 45º ruler or a 45º line on any ruler.
