After hiking and camping with a PC snapsack a few times, I decided I didnt like having *yet another* strap diagonally across my chest, and set about making a two-strap knapsack.
I bought some canvas, cut to to shape, dyed it darker with coffee (didnt come out as dark as I would have liked, but at least it isnt stark white now), and "waterproofed" (i am sure water will penetrate eventually, but water *does* bead and run off the treated surfaces) the exterior faces with several coats of melted beeswax (melt the beeswax in a double boiler, paint it on, then melt it into the fibers with a heat source. i used a hair dryer).
The pattern is just a basic folded "envelope", but it is roomy enough to hold a spart shirt, some extra socks, a bowl and spoon, as well as a good amount of food. Im sure I could shove more stuff in there if I had to.
Now that it is getting cold in New England, I want to carry a third blanket. Rolling it up into my bedroll would make the bedroll unweildingly thick and bulky. I can fit this third blanket under the flap of the knapsack and tighten things down with some leather thongs
