I dont want to carry anything to class so I have a couple of plastic totes that fit in my rolling carryon suitcase and only the rulers that fit. For my last retreat I had four items, one suitcase held tools and projects, one clothes, one roll around table and my featherweight in a case. Neat and tidy and all rolled. I made two quick trips and was ready to set up.
I also have a shoulder bag that holds a large cutting mat and the 24 inch rulers but only a long retreat calls for that one.
