I made broomstick skirts to wear when I was a teenager (long time ago!) Just find the size for your waist band and gather the fabric to make a full gathered skirt. (Can also be made in multi-layers of gathered rows.) Determine the length, hem and there you are. Easy-peezy. They were called broomstick skirts because when washed, you tied them around a broomstick with twine to get the wrinkles..... Most of our clothing then was starched and ironed! This brings back memories.
