This is part two of the anatomy lesson from the last post! A classic mistake we see on a regular basis with pleated sunburst accordion skirts has to do with the side seams and the center back zipper. If you read my previous post titled Bias Skirts 101, you understand there are two ways to cut a full circle bias skirt. One way is to cut two half circles, one for the front and one for the back. Doing it this way would leave no margin for error since you can only put a zipper on the side seam and the grain lines will match up.
