I haven't taught jewelry in over 20 years. Three ideas come immediately to mind.
1) put a powerpoint together.
2) get a demonstration table, which essentially is a table with a tilted mirror overhead. (our home ec teachers had one)
3) Do a live feed with a video camera that gets projected onto a screen or TV (of course make a video of it to save to show the next group). Live feed isn't that hard to do, you need a camera, tripod, cables from camera to either your computer, tv or projector (ask your tech folks).
