Sounds like a great class. A phone for pictures is a must, for when the demo on loading the quilt is shown. It took me several practices to load a quilt on my machine, I would just load and unload one for practice, which if your purpose for this class is for rental of a machine in the future, you won't have that opportunity, so lots of pictures will allow you to reference when you are loading your quilt during your rental time. If you do have your own long arm and this class is a precursor, the pictures will help you when your home and on your own. Enjoy your class and have fun.
