Step 6: CONSTRUCTION of Front and Back Shell
a. Pin A to B right sides together for both left and right front
b. Sew seam for both left and right front
c. Press seam allowances open
Optional: Recommend fusing interfacing to top corner of B on left side where buckle will be inserted later for reinforcement.
d. Insert piping into bias binding and sew or baste in place
e. Stay stitch and clip curves on C & D in seam allowance only
f. Pin baste piping along seam line between C & D right sides together, and stitch in place.
g. Press seam allowances open
h. Top stitch on each side of piping at ¼”
i. Pin center back right sides together
j. Sew center back
k. Press seam allowances open
Optional - I recommend reinforcing the left front overlap with fusible interfacing on the wrong side so it can withstand the insertion of the buckle later.
