The yardage required to make a wrap skirt can vary depending on several factors, such as length, width, size, and fabric width. However, a knee-length wrap skirt typically requires around 2 to 3 yards (1.8 to 2.7 meters) of fabric. You will need more for a longer ankle-length skirt or a fuller silhouette, while a shorter or narrower skirt would require less. It's always a good idea to consult the pattern for accurate fabric requirements for more precise yardage requirements. Remember that this estimate assumes a fabric width of 45 inches (about 114 centimeters) to 60 inches (about 152 centimeters). If the fabric you choose has a different width, you may need to adjust the yardage accordingly.
