I have recently fallen in love with painting on smooth panel boards as I feel I do not have to use as much paint. I paint much looser than when I use a canvas.
However, I own many canvases and would like to still use them. I have tried adding more gesso to them to help make the canvases smoother, but they still take a good amount of paint (more so than panels). Is there a product out there I could prepare my canvas with that will give it a smoother texture to paint on that would work with both acrylic and oil paints?
