Hi John,
Not to be contrary to one of the more experienced, but I had received 
guidance from another leather expert also on the technique I used. He 
mentioned paring but reserved the technique to those with much experience as 
it could be devastating to those you had little or no experience as it could 
result in too thin, uneven or punctured leather. Using water aids in 
increasing pliability of leather and further allows for the use of thicker 
hides. The problem comes with tight bends as I indicated and this requires 
patience.
I forwarded pictures to Keith of my technique and the resulting finished 
product. It has been over 5 years and the leather finish looks as good as 
the day it went on with no release, bulging or creases. My leather came from 
Heritage Upholstery who use the real thing.
I guess there are more ways than 1 to "skin" a cow.
Best regards,
 Alex
