In my teaching experience, one of the hardest concepts to explain is "needle drift". Needle physics can be a difficult concept for piercers to fully wrap their heads around. I attempted to address this in a previous blog entry, but I believe the following animations are more likely to be helpful to a piercer than my initial entry on the subject was.
My brother was kind enough to make animated .GIF files for me. These .GIFs demonstrate, simply, the way needles drift through surfaces.
My suggestion to piercers who are viewing this and still having trouble with it is to use a large gauge needle on a piece of foam board or a thin piece of flexible silicone. You will feel the difference, and this will influence your bevel orientation on every piercing.
My hope is that the visual learners in the piercing community are helped by these animations. My sincere thanks to my brother, Chris Saunders, for producing these for me!
