Bark Tanned Deer Hide

Well...I have always wanted to try working with bark tanned deer hide, and I finally picked up a really nice one to try...and I have to say that Im kind of disapointed. It is really soft in the hand, and my hat is off to the tanner, as breaking this hide was executed with the greatest skill, but it doesnt work at all like good russett english oak tan, and theres nearly zero memory, which makes it pretty difficult to use my marking wheels etc to lay out stitches and the beautiful dark color makes seeing what faint marks that may be there about impossable...I can see now why so many creative techniques are used by craftsmen making and selling "bark tan deer hide" pouches...like whip stitches...heavy cloth linings...heavily weathered and antiqued finishes with layered patches and mixed leathers etc...the stuff really doesnt seem to lend itself to more traditional techniques, at least not for me so far.

That said, I am really intrigued by alot of the similarity I see between the bark tan I using and several original shaved hair pouch examples I have, including the reddish color of the hair! Im now wondering if similar bark tan deer is what was originally used on many originals?
The workability and memory may be different because of the original "oak" versus the now common "hemlock/sumac" bark tans now employed? ( although in the north country, like French Canada, I think the hemlock/sumac barks were always predominantlyused as oak was not readily accessable...)

Well, these are just my preliminary observations, more to follow later...
