My suggestions are these, avoid bags that are too large, because the originals aren’t. Bags that are too fancy, rarely look correct with most common cloths of the past, and quite often look like your wife gave up an old purse. And, quirky overly rustic bags almost always look contrived. One of my favorite bags is a copy of a very old, and fragile one owned by a good friend that is made in one piece. The front, back, and flap, are one strip of brain tanned leather about six inches wide. The strap is the only part that is added.
