Great! Thanks for the reply:)
I've made a few smaller bags, kind of as test runs, so to speak, just to see what happens with the the folds/edges and how the top would work, although I haven't made one with a frame. I think I've got those things worked out in my mind to the point where I'm ready to give it a try. This will be my first "real" project with decent$ leather (I've made several purses and messenger bags). I've used mostly softer, thinner 4-5oz oily leather. I knew I wanted something thicker and harder, but not too thick. I've seen similar bags made with 8-10oz bridle. Do you think that would be a good type of leather to use? Again, I want in to be rigid to a point, but not like wood!
Wickett and Craig has 8-10oz bridle sides on sale in a few colors due to overstock for $140. I've heard they can/will thin it, or part of it, to whatever you want. Seems that would be necessary for the gussets. Can you please take a few more pictures, particularly of the gussets and the openingframe of the of the bag? Also, I guess the seams on the gussets are exposed? Seems like it would be difficult to sew it inside out and evert it.
Thanks so much:)
