So you think you just drafted the perfect Peplum or Circle Skirt, only to find out, when sewing, there's a few flaws. Correct those flaws before you start sewing. When you align the CF to the CB it looks great. Wrong: You need to abut the side seams to see the flaws. Once you do that you can see how the tops have a peek and the bottoms have a valley. See the pictorial below. Just smooth out those peaks and valleys and your project will be successful.
