After my trip to Wisconsin I was still interested in determining whether or not I wanted to take NeoArt watersouble wax pastels from Caran d'Ache to life drawing with me—for gesture sketching.
I had some discontinued paper I was running through and so I picked up a stick and did a little dry sketching, then I dipped the tip of the stick, which is blunt, in my painting water, and stroked a couple times with the wet stick.
It was a fun experiment. I was working from birds in my mind. I think if I want to make large gesture sketches at life drawing this is something to pursue. As a regular thing in life drawing, however, I probably wouldn't do a lot of it because to work it needs a paper of high enough quality to take some water.
I could use some of that recycled Richeson watercolor paper I got for such a deal last year. We'll see.
If you enjoy sketching with large flowing lines you might enjoy working with NeoArt sticks in this way.
