I'll be attending a small 3 day crop in September. I'll be doing the digital thing, and I've been asked by at least two people to do a digital demo/lesson for beginners. I've decided that the best thing I can do for them is to teach them enough to become basic paper imitation style digital scrappers. I'll teach them how to open a new document, drag and drop, how to cut paper into rectangles and add drop shadows and a teensy bit of journaling with the text tool.
While I'm able to teach a great deal more than that, I know that nobody can learn more than that in one sitting and then, they will need time to practice it.
