They are much more portable than other mediums. My materials are packed still and will be for a while longer. This gives me a creative outlet and can serve as sketches for more ambitious paintings.

Not a great painting, but I can certainly see where I’d like to take it! Next time I’ll bring a stool so I don’t have to sit on the ground.
