Are dairy glues or any other natural kind that might've been used any more water-resistant than hide glue is? IIRC dairy glue has a lime element to it- if so, maybe that affects its solubility? Leather might respond a little better to waxing to seal it, but then the issue of the interior still remains if one is talking an outer 'skin' on layered linen. Two layers of leather might work- both flesh sides in, facing one another. But then is the glue really a significant element with leather? It can saturate fabric readily enough and does seem to make a significant difference, but I've never found it to permiate leather terribly well so is its presence enough to offset the issues?
