Some have used rolling suitcases to carry their machines in. I don't typically take my good machine to a class. I take a small, inexpensive Brother that I got at Walmart. I have a small carry cover that I put on a trolly to move it and my "stuff" in and out of the classes. The exception is if it was an embroidery class, then I put the Big Brother in a large serger bag that I pad with fabric, thread and anything else I think I have to take.
