Sorry your class as a dud, I'd give it a try and ask for a refund.
Sounds like a 'quilting class' to took once during an Elderhostel craft/vacation where were could try different crafts during the week if we wanted to. Quilting class consisted of the instructor handing out kits for a small wall hanging and giving us a trunk show of her quilts. We were set up in a tiny corner of a room with one little table which bearly held our sewing machines. I quickly got out of that class and into another. Accomadations were great and so was the food but I choose the place because of the quilt class. Live and Learn I guess. May in Jersey
