Hello fellow leathercrafter, I'm curious if anyone has a link for a pattern similar to my image here, or maybe some experience making one.

I've made plenty of tote bags but not specifically this type with the seem on the outside. While it doesn't seem overly complicated, there is some interesting sewing steps near the bottom where the side seems connect to the piece on the bottom which wrap up and into the bag. This seem is how the side stays closed at the bottom.

Please don't mind my photoshop skills lol. Hope this all made sense! Thanks!
