Hi Becky! First of all, this project was made from silk charmeuse, which I wouldn't recommend for a first project! Starch helps tame it, but it's still not the easiest fabric to work with! Anyway, I shaped the row of lace ovals and diamonds, then cut the fabric from behind, as I demonstrate in the class. Then I made a strip of pintucked fabric wide enough to fill the "holes," placed it behind the lace, and stitched the inside of the open lace shapes, again, like in the class.
