First I would tell them to relax, Quilting is a journey not race or contest. Things they need to know. What tools are a must have, how to use the tools, how to square up blocks, and quilt tops, difference between iron and press. How to get an accurate 1/4 seam, basic cleaning, maintain of machine, what are color values, how to read and understand a pattern, a list of common terms and what they are- half square triangle-WOF-bias- etc. I'm sure there are a lot more. My be ask them to make sure they know there machines before the class. Good luck with you class
