the front panel flat with the right
side facing up. Align the back panel on top,
right sides together. Align
the open edge of the zipper with the
front panel fabric, right sides
together, pin in place, and sew a
seam along the open edge of the
zipper just as you did before.
Unzip the zipper,
align the front and back panels
together, right sides together, and
sew a 1/2" seam along the side and
top edges only. Turn the fabric
right side out; the outer shell
portion is now complete.
