Melissa from Blank Slate Patterns and Melly Sews shows how you can draft a skirt pattern based off of your own body measurements. Her tutorial includes photos for each step for creating a basic short, straight skirt. Then, she shows how to modify that pattern to create several other styles of skirts, including an A-line skirt, a yoked skirt, and a skirt with a flounce. Go to her blog for the how-to.
