I know you can do it too. Just remember, if they signed up to listen to you, you know more than they do. The poster for the class should say (for instance), Quilting 101, accurate cutting and how to read your ruler. I'm not sure exactly what you want to focus on. When they pay their money they should get the hand-out for what they'll need for the class: mat, cutter, ruler and fabric if that's as far as you're going. Say on the paper if you're going to make up kits for the class. They can buy the stuff when they get there or bring it themselves, their call. If you're starting them from the very beginning leave plenty of time for questions. They're lucky girls. Learnin' from a pro.
