The Bjorkman’s are offering a good idea. I will only add that when I
was an apprentice, we were taught first to SAW. Use a 3x3 inch sheet
of 18 gauge copper and have your students saw straight lines, wavy
lines, zig-zag lines, circles, hearts, etc. Until they can do it with
ease and proficiency.
It is the most basic and necessary of skills, which if not taught
properly will hinder the most creative mind and doom any attempt at
jewelry making to poor craftsmanship.
Feel free to email me off-forum for curriculum ideas and projects.
I’d be happy to share.
