Overall the class was great fun,and much more difficult than I would have expected. Much of the difficulty revolved around the handling of the paint.
Here's what I've learned so far:
Your process and outcome will depend, to some extent on whether you find a tube of the purple Torrit Grey or the warm Torrit Grey. They all look the same on the outside.
Regardless of the tube color, the biggest constraint is the ground
you use. One of my students, Kay brought some New Traditions art panels
to use in class. For those of you have used any of the the NT oil-primed panels, you know that the surface is more tightly woven and much
slicker than an acrylic canvas. It makes all the difference in the world.
Below, I used a scrap of NT oil-primed linen and brushed a little of each of the Torrit Grey colors on it, then went in to wipe out the color. Both lifted beautifully. Had I know this in advance I would have been more specific about the type of support in my materials list. When I am in open studio, or doing a demo, I typically use whatever cheap canvas I pick up,since I am pretty sure I will throw out the canvas after the studio, and the NT panels are a lot more expensive (a note here: I have used NT panels exclusively on my commission for a number of years). Live and learn. I plan to work up a Torrit Grey painting on the NT panels,with the warm color, and I'll add to this thread when I learn something more. I expect that any slick surface will enable color-lifting, but if I were you, I'd check it out first
