Over the last few years, first painting as a hobbyist and lately as a minor art master (painting every day), I have tried many different surfaces to paint on. At the moment my favourite is hardboard. Why? Well, I like to paint on a large scale and I find that the stretched canvases are just too soft and pliable. But, most importantly, I choose to paint on hardboard because it is cheaper and it gives me the freedom to make mistakes and start over. A few layers of white PVA covers anything!
Most of my animal paintings were done on hardboard.
All my newest portraits are done on hardboard too.
What do other painters out there prefer, I wonder?
