Sorry, forgot to mention that CaptJas aka James Rogers' stuff is also sewn like they did things in the 17th and 18th centuries and that is another good reason to closely examine the articles he makes.
Most of we non apprentice trained leather workers make mistakes that trained workers are taught not to make and/or we don't do things quite like they did back then.
Eric Myall, who was the Saddler at Colonial Williamsburg for 22 years, is a friend and mentor of James. A year or so ago, James helped me obtain a full set of the 18th century leather working DVD's that Eric made. I was elated with them to learn many little things and a couple of larger things. While Eric's DVD's are not for every modern leather worker, they are fabulous for anyone wishing to make 18th century leather work correctly.
Now, since leather work did not change hardly at all between 18th century and the 1820's, if you find you want to do more period correct leather work, I heartily recommend Eric's DVD's.

P.S. Some day when I grow up, I hope to make all my leather work as good as James Rogers does.
