An easy way to add a colorful piece to this pleat is to cut a larger piece of fabric
than needed. (keep the grain straight with the seam ) Lay this right sides together
over the Side panel . Sew and flip it over in place . Neatly align the fabric, pin
and baste edges in place. If the dress fabric is light you can leave it underneath.
For velvet trim it away. You can see where the embroidery has shortened the panel.
Remember to follow the edge of the vilene when sewing the dress together.
