Today was rainy and lazy. We had an alumni of risd and ehp come in and do a fresco painting demonstration. She has been living outside the US ever since she graduated from risd.
Fresco painting is when paint is applied to semi-wet plaster and then as the plaster and paint dry they become one. This is why frescoes from as far back as the roman era are still preserved. If paint was applied to simply a dry plaster wall there is a much larger chance that it would flake off.
Above is a fresco I saw a few weeks ago in Arezzo.

Also today, I started drawing on small plywood panels with pen and really like it. We'll see where it goes...
