Thanks for all the comments guys. It may mean I'm getting close.
Jeff, your comment regarding the binding was something I did before I thought of the free style flap. I was using a thin piece of moose hide to practice what we had discussed awhile back and after looking over a couple of Mills bags over the years I thought it would look 'right'. Of course, trying to make everything look old and incorporate some details may end up accomplishing the opposite. Sigh, I keep plodding on.
James, yes good barktanning is getting expensive, but I find it very good leather for about any period you want to portray.
Jerry and Kermit, as far as putting the binding on it was really a discussion I had with Jeff regarding how he accomplished his binding and after seeing the same technique on other maker's bags I thought I'd do the same on this bag. I just simply lay a strip of my binding lay face down on the face of the leather portion face up. Face to face. I then decide to sew the binding about a ¼ inch from the edge. Then you fold your binding towards you and tuck to the other side of the lip (in this case the inside of the bag). What I did next was to begin my stitching from just under the binding on the face side and continue to the end. If you use your linen thread close to the same color as the binding it gives you the impression it was blind sewn until you look closer.
Thanks for all your comments and suggestions. They’ve been useful and as always, the learning process continues.
