Everything I know, I learned from somebody else. I read it in a book, saw it on TV, got it from the internet, or learned it in a class. I apply those methods to new things that I learn. I can now pick up a book or pattern and figure out an easier way to come up with the finished product. All those methods have melded together in my mind like a pot of leftover stew. It is rare that I even remember where I learned a trick, and I am happy to share what I know. Do I recommend books, TV shows, etc? Yes, I do. Do I feel that I have to without committing a crime? No.
I have been a teacher most of my life. I have taught a variety of subjects, all of them creative. I fully expect those that I have taught to use that knowledge in any way she or she sees fit. The real crime would be to let that knowledge die for lack of use.
