I carry a small sketchbook and pencil or fountain pen in my bag at all times, because one never knows when a quick sketching opportunity may arise! I also keep a mini watercolor kit that holds a 12-color palette (hacked into a mint tin), brush, rag, and small water jar. It all fits neatly into my father’s old pocket-size, leather camera bag and is perfect for a luxurious 15-minute window of opportunity. On the days when I actually plan to go out and dedicate significant time to sketching or ‘plein air’ painting, I usually take more items including: multiple sketchbooks, a 16-color travel palette (shown below), an assortment of brush pens and fine-line markers, my monopod stool, and sometimes even a light, folding easel.
