I've become an information junkie and am always scouring around for new learning tools. Here is a good DVD by Sandra Betzina. What I like is that she describes jacket construction on real jackets, shows a teaching presentation then goes to the machine and sews it up. I personally don't love when instructors jump from one completed step to the next, I want to see them on the machine making it all work the way I will when I do it myself. Sandra does it all from soup to nuts. I find myself playing chapters during construction and it really helps, especially with sleeves and linings. I consider this one a good investment.
