The bottom row of petals (there are six) is attached to a short skirt, the length of the one from view B. Instead of making it a full circle skirt, though, I used just the two side panels. Each of the bottom petals was slightly gathered at the top so that they fit around the circumference without overlaping.

The other four petals were overlapped around the waist. They were sewn onto the waistband first, then the waistband was sewn to the rest of the skirt. (I did it this way because one petal needed to reach the end of the waistband where it overlapped on the end, in order to help cover up the gap at the side.)
