There is a great series on making clothing in an open-source library I recently found.
A Complete Course in Dressmaking by Isabel De Nyse Conover.
Here's the lesson on making skirts.

It does make reference to skills taught in previous lessons (all lessons are available in the library). While it doesn't give you a pattern, it has a lot of information about structural aspects (eg., grosgrain ribbon waistband) that I think are helpful to making a long-lasting garment (as opposed to today's fast-fashion emphasis).
Though the title says "Dressmaking", it's a basic sewing course and there is a lesson on conventional men's clothes of the era, as well.
For Folkwear patterns, I have found good used deals on Ebay and Etsy; often they are uncut.
