This is the skirt pattern that I created to use with the reversible skirt tutorial. But you can use this to create a simple skirt pattern for yourself. There is going to be a little bit of math to figure out for the skirt pattern. To draw the pattern, you are actually only going to draw a 4th of the whole skirt. The measurements include a 1/2 inch seam allowance.

1. Measure the waist circumference and desired length of the skirt. Or grab a favorite skirt and use measurements from that.
waist = (waist circumference ÷ 4) + 3 inches
bottom = waist x 2
skirt length = measured length + 2 inches
3. Once you have your measurements, use scrap fabric or butcher paper to draw your pattern with the measurements.
