Jim thanks for the response mate.
I followed you up to the point of "Once both sides of the leather covering are formed and trimmed...". Do you suggest stitching both sholders? It makes sense to but I'm just checking. Remember the flask is heavy glass and can handle any stress the leather could give it through shrinking (I imagine so). Will I need to glue it to help to stitch it? I was aslo curious as to percentage a piece of hide will shrink after being wet, that is if you don't nail it down (nice suggestion btw).
Also not sure what stitch to use. I was thinking a figure 8 with two needles.
Interesting you used a powder flask as example. The company that made the flask, James Dixon and Son, also made powder flasks. It's an olde Flask =]
Thanks for indulging the new kid.
