RE: Apprenticeship??
It use to be many many years ago, you were lucky if you could find a book to learn taxidermy from.
today there are hundreds of video tapes and books and a few schools.
I learned when I was in my teens by working during summer vactaions from ataxidermist that I cleaned shop and helped around, until I saterted doing little things at home. so you can say I learned on my own and took a correspondence course that cost me $12 in those days from JW Elwood Taxidermy school. You'll find out most taxidermists my age also went through the same thing.
I don't know anyone taking in apprenticeships as an apprentice will be future competition.
You may have to go out of town to get some lessons, i don't know if Bill Yox is still offering that.???
