I have just noticed on two of my saddle bags (a Nelson and a Barley) that the straps are not set equidistant from the edge of the bag flap. Is this a machinery/setting out/design requirement? e.g. two finger widths to one corner reinforcing collar and three finger widths to the other. I have another Nelson in the Garden Shed and will check that tomorrow. In practice this means that the bag hangs slightly off centre. This of course can be just part of the character of the hand made bag and is not a serious issue, but my curiosity has been roused.
