I wondered how many people know what is under their painting. The easiest and most popular ground for oil painting is ready made from acrylic paint. It is easy but I don’t like the look or the feel. My gesso recipe has been used since before the Renaissance. Hide glue and chalk. I add iron red for color.
I learned it from a Japanese egg tempera painter in New York who now works with software and images on line. Thanks Kenji.
