making one to use instead of my horrible modern bag. What kind of leather should I use. I usually use normal veg tan then dye it, but i dont want to have to dye it, and i dont want it bleeding on the stuff inside. What kind of leather should I use, where should I get it and how thick should it be?

thanks

Hi,
It would help if we knew- What period? Status? Military or civilian?

Regards
Eric

quite a few periods- I'll be making quite a few bags. its not the pattern that i need, just what leather would do the best job. the first one will be civilian, byzantine if it means anything to you. thanks :)

If you are dyeing them with period colours then bleed is not realyl an issue, exp with black as that is a chemical process combining the tannin in leather and the iron in the blacking, ie it is not paint.

Also, dependent on which ear leather was often only dyed on the visible side to reduce the use of expensive dye on surfaces that were not seen.

Black is easy, brush a solution of ferrous sulphate onto the leather and hey presto grey/black a quick rub with some oil and it is lush.

Ferrous sulphate is available at garden centres as a soil improver, around a quid or two for a kilo.

try it out on samples to see how concentrated you want it.

You can also use 'the black liquid found underneath grindstones [the water well]' ie it is the iron filings that have to some extent releases iron ions into the water.

I suspect the ferrous sulphate to be easiest acquisition.

what thickness veg tan should I use? 2,3,4 mm? I would like it to be relatively soft.

thanks

No idea mate, I am no leather worker, I am a dauber so in my readings I have found medieval leather dye recipes.

My work here is done ;-)
