I will tell you my experience.
First year, I demoed how to make a byzantium chain mail bracelet.
It took about an hour, and I had about 6 people watching me.
Since it was after dinner, we were all pretty mellow and
while it wasn't perfect, it went pretty well. It wasn't a class,
just showing them the basics. We had a great time.
Second year I demoed how to make a sculptural rose.
While my demo was absolutely perfect, I was scheduled
at the same time one of the BIG artists were doing their demo.
So I had what could amount to a "pity crowd" (eg: my buddy
Patty
).
Oh, and I burned the crap out of my finger picking up the wrong end of
the rod during my demo.
Anyone else want to share?
