Hello the camp...I would like to add a word of caution about chemically aging some of the inexpensive import leathers...recently some of these imported "craftsman" grade sides are quite dry in the hand, and they can really react badly to harsh caustics like oven cleaner,and even to standard home made iron/vinegar or commercial spirit dyes...by this I mean that after chemically ageing it,or on some of the sides even after coloring it,the leather often dries and shrinks up so much that when its flexed it cracks so badly and uncontrolably that the bag is actually ruined...and some of the thinner strapping can actually dry so badly that its prone to tearing.
If you opt to use these imported economy leather grades, please experiment with any artifical aging process first to see how that particular side will react...age a swatch of it like you intend to age the bag, set it aside for a few days to dry etc...and see how it has reacted.(note: each side may react differently, so this test needs to be done with each new side.)
Since a bag is usually antiqued "after" its made, it would really be a sad thing to ruin it at that point. Again, some initial experimentation may be needed to get the results you want.
