Interesting article, thank you. I'd be interested to know how the theatrical version you have here differs from the historical way.
I made a 1860's gown years ago using cartridge pleating. I did the hand method but cheated slightly by using gingham ribbon as a guide. It had the added advantage of providing a bit of extra support to the fabric when attaching to the waistband. It also made it a bit quicker to put together by not having to create a marking guide.
