Hi there, You can actually use the tutorial to make the skirt any length you want.  I just did a short skirt because I wanted to be able to fit all my work on screen.  When you draw your side seam line, you’re going to substitute your desired length measurement.  For your skirt, measure from your waist down to where you want the bottom of the skirt to hit.  Whatever that number is, that’s going to be the length of your side seam.  I just use my measurements as an example in the tutorial so it would be easier to explain. We’ll eventually have more tutorials showing you how to alter the basic skirt to get other styles.  Good luck with your skirt and we’d love to see a picture of it when you finish.
