I haven't hung out here regularly but have seen Zimmer's name mentioned a few times. Then, just the other day, I found this site of his and have since "searched" this forum to learn more.
The guy has never sewn before then just magically starts making packs one day that not only look to have professional craftsmanship but are pieces of art to boot. I'm just shaking my head in awe.....and envy. A true artisan who appears to be exceedingly nice to boot.
EDIT: I don't want to take away anything from the other talented members here. It's just that one doesn't see this kind of talent appear overnight very often.... in any arena.
