I'm planning on an artshow in 9 month. After than I'm going to set up model kits for kids and educators. I might do worldbuilding presentations at science fiction cons. I'll explain how to take latitude and axial tilt into account when mapping science fiction and fantasy worlds. For those goals I need to make a lot of models, so I'm carrying my card modeling with me. When I meet with other writers I fold and glue. I even had it with me at church this am. Not during the service, but during donuts and coffee. Here's my moble setup. I've got two strips of hook Velcro inside a briefcase style camera case to hold tools. It's designed with movable compartments for lens. The parts I'm working on go inside the old video case and the packaging from a lightbulb. I have glue in a small bottle purchased from a craft store. I hit the after Christmas sales. There is also room for stories I'm working on, a calendar, copies of my published book, book swag, and my business wallet with Square to take credit cards.
