[This page is part of a mirror of my Canvas learning system pages I created for my Drama 112 Intro Stage Makeup class at DVC.  If you want to use this content for another Canvas class shell you can find it in Canvas Commons by searching for “Tara Maginnis” and you can download all or part of this directly into your shell with all the extra cool formatting of colored divider lines, right side embedded Giphy animations, etc. already put in, if you are working with a different system, it is ok to copy and paste from here, and then customize the pages as you need  for your classes].
