I never leave home without some art supplies - even when I'm just taking my daughter to swim practice! I have a small sketchbook and pen that I carry with me at all times. In addition, I have two traveling art kits that I carry whenever possible. One of them is a 12"x4"x2" art bin that is divided into several compartments. I carry the essentials - pencils, a couple of markers, glue stick, small art tools, small pieces of ephemera, and several other items. The bin is the right size to carry most anywhere I go. The second kit is a scrapbook briefcase that I've filled with various kinds of paper, a watercolor set, brushes, paper cutters, rulers, and much, much more. I use the briefcase when I'm going to be away for a week or so. It is so relaxing to me to sit at a bench, café, hotel room, or anywhere else and work on my art work. The following are examples of the artwork I've created on the go:
Pencil drawing, watercolor painting, and calligraphy
Colored pencil zoomorphic Celtic drawing, letter stamps and hand lettering
over a watercolor background and journaling
Pencil drawing, rub-on globe, and punched stars over a watercolor background and journaling
I'd love to hear about your art work on the go!
