New painting in process. Last month I did a Chinese Karst hills scene in a 3 x 4 ft format. This is 2 x 3 feet which makes for easier handling and I have found a plywood from China that is thin, light, very strong and is perfect for this size painting. Shop at Lowe's- 4 x 8 piece --3 cuts and you have four 2x 3 foot panels plus two 2 x 2 foot panels for $11. Add several layers of Gesso and get going. No need for back bracing. This was done in about two hours - out of my head - but I did do something similar a month prior.
