so you can see the natural fall of the fabric. fold the raw edge under along your gathering stitch and pin it to the lining. you want the pressed edge of the lining and the folded edge of the skirt to line up.
you will have extra skirt fabric between those pick up points like in the picture above. gather the excess skirt fabric so that it fits between those points, and fold the raw edge under and pin as you did before.
once you have gathered and pinned the hem, stitch the skirt to the lining using a ladder stitch and your done!
hope that helps someone! and as i said before,
