I have been giving lectures with a powerpoint presentation to bead societies up and down the West Coast for years. These listings are for recordings of lectures I have given live on Zoom during the pandemic. I may give live lectures again someday. For now you can purchase the lecture and I will send you a link to an unlisted recording of the lecture. I hope to do my drilling class, "Benchtop Lapidary Techniques for Jewelers" at some point in the near future.
