OK, making 18th century shoes!
Yes I've considered it but it might be the next millenium before I have a go. However if you are all fired up at the prospect of making your own historical footwear then Nicole Rudolph (The Diary of a Mantua Maker) has written a book about making 18th century ladies turn method shoes.
While not a 'how to', the book does detail the methods Nicole has used herself.
The book, conveniently is available both as a PDF as well as in print.
Get all the details at her blog.
