Yes, i realized that i didn’t address the fact that one can also save selections. Still not enough time in those classes!
I am in the process of re-recording it, and the recorder crashed on me AGAIN. I finally have it recorded, and i am in the editing process right now.
I might definitely consider a class on layers. I’ll have to look at all that can be said, shown and explained about layers in an interesting manner (i don’t want anyone to fall asleep during the presentation!) and will have it on my “to-do classes”. Thanks for the suggestions.
