I'll be adding to a list of everything I use & how I use it in the classroom soon. There are so many useful tools available. Thanks @Karl Hubbard for asking about my stencil process. I'll upload a full tutorial soon. I've been using this ai stencil app this past year for almost all of my tattoo prep. I do check them closely though, because the ai can get important details wrong occasionally. I often redraw parts in procreate, but this still saves me a lot of time! You can create stencils, copy them & paste straight into procreate on a new layer. And they are the correct size already. This is made by tattooers, for tattooers - https://tattoostencilpro.app/
