My favorite take to class rolling tote is a large 4 wheel "vehicle" which I purchased at Target years ago. It is square on 4 sides but taller than wide. It is encased in a wire grid which I covered with a firm fabric on the inside. I use it in sewing classes to hang items on the sides that I think I will need. My FW fits inside as well as my tool kit and fabrics. It is super easy to wheel around./
