What fabrics are you using? The thickness/heaviness of the skirt could be a factor, and I would use a different method for thin or lightweight fabric than I would for a heavy shell. I'm assuming the lining will be lightweight/thin in either case.

Thanks for responding. I would be usiing cotton velveteen or wool which I think would be a medium weight. Yes lightweight lining.
