In this video I am going to attempt to reverse-engineer a foraging bag from scratch using leather and canvas - constructing the bag, and then constructing and attaching the leather strap. I may make the pattern downloadable (donations accepted), once I work out some of the measurement kinks. But for now I am pretty sure this video demonstrated the just of how to put something like this together.
It would be better to use waxed canvas but that is a whole another process in itself. Perhaps I will do that in another video. This is not a very primitive/stone-age project, but I think it is an interesting bush-crafty one. Maybe I will think of a way to "re-wild" this bag and make it more rustic - primitive.
In the third video I show how to modify both the bag and strap so that they are detachable. That way an untreated, dirty, or torn bag can be replaced or swapped out - as well as the strap.
