Carrying stuff...
Well, if you look closely at my little avatar, you can see that he is carrying a square shoulder bag with a triangular flap. This is from a Schwenkfelder catechism (Pennsylvania) dated Feb 1, 1787. Whether it represents the student himself (David Schultz), carrying his books in the bag, or just some man walking along picking apples, I don't know. I also don't know if the bag is supposed to be leather or cloth, but with the pointed flap, I would expect leather. Also note the universal German use of the walking stick. Men, women, children, all very often seen with walking sticks.
Now, most of my "studies" of period images is focused on things German, both in Europe and America. Other than this single example, I don't know that I have seen any other instance of an ordinary German civilian with a shoulder bag. Well, maybe one more, I'll have to dig and see if I can find it. I'm sure they were used here and there, of course. I do recall an English image of someone handing out handbills with the bills carried in a shoulder bag. I've also seen a scissor/knife seller carrying his wares in what appears to be a basketry "box" slung on a shoulder strap. It was certainly not an unknown concept, but packing around stuff in a fabric shoulder bag does not seem to have been that commonly done.
Up to the middle of the 18th century or so, it was nearly universal for military knapsacks to be of the one strap variety (worn more on the back than down by the side). After that, knapsacks began to be of the more familiar two shoulder strap variety. And I have read ample period references to non-military folks going out into the woods with their knapsack on their back (but not their haversack under their arm :wink: )
When I look at period illustrations of folks carrying things in general, like going back and forth to market, or in the case of the Salzburger Exulanten, being forced from their homes and trekking to Prussia (and some came to Georgia), I see snapsacks. Lots and lots of snapsacks. Sometimes, the "snapsacks" are just sheets of fabric (possibly blankets) with their belongings rolled up in them, with the ends of the sheet twisted and tied up into a "shoulder strap". I also see two-strap knapsacks (usually square, but sometimes of the "Alpin Ruecksack" variety). Pack baskets are also often found... though I have had people SWEAR that such things were NEVER used in Colonial America, as there is no proof of them here...
As a personal thing, I DETEST shoulder bags. Swinging around, swooshing in front of you every time you bend over even slightly, no matter how high or low you try to hang them. They are a pain. I don't even like a shoulder shot bag unless I can attach it to my belt to keep the stupid thing still! I have started to make myself a leather and hair-on goatskin knapsack, which I'll eventually finish in which to carry my "stuff". I have experimented with different things to see what works best for me, including blankets on a blanket sling ("tumpline" or "hoppus"), which is ok, but I have found a properly fitted knapsack works better.
