Symmetry Twins

Did one of my favorite portrait projects again this year with my 2nd graders. Here is my original post on the lesson, no changes were made because it's just that awesome.

Really the best part of this project is the element of surprise when revealing that they are creating a twin on the other side!

So here are my questions...
Number 1, is tracing okay in the art room when this is how it's used? And, number 2, how do you feel about letting them make themselves as devils?
