(Sidenote: the Android Google Pixel 2 camera is dope AF for taking photos of paintings and artwork. If things look a bit clearer above, this is why.)
I did like painting on smaller pieces of Yupo but for range, larger pieces (around 8 x 12 or so) work much better. It turns out you can get huge rolls of Yupo, similar to rolls of mylar, for larger work.
More oil on Yupo discoveries:
Will oil paint crack or split on Yupo once dry?
No, it bends as easily as the plastic it’s sitting on. Freezing weather would likely cause cracks, but that’s all I could think of. It’s been a few weeks since making my first painting on Yupo and it’s holding up beautifully.
Since plastic has extreme longevity (think of all the pictures of plastic in the ocean and its tendency to never biodegrade) oil paintings on Yupo could last for a long time. I don’t see yellowing as a problem, as long as the paint utilized is pretty good. I’ll get back to you in a couple years.
Does Yupo work for thick, heavy layers of paint?
The answer is YES, it works just fine and can support quite a lot of paint and impasto medium, up to about half a centimeter at highest. I’d recommend the Yupo heavy version for painting with thick paint.
The smaller Yupo surface worked well for experiments and compact painting, so I decided to branch out and try a larger size.
What else works on Yupo?
To be honest, just about anything. Watercolor pencil looks great, acrylic ink pours on and Yupo holds the color brilliantly. Copic markers work and since they are alcohol-based and the paper is smooth, they blend even more fluidly.
