I paint over old paintings, watch me!

A painting doesn´t last long with me, if not sold within a year I repaint it. Because an old painting is the VERY BEST underlayer for a new one, to me. I save some small parts that I mask with tape while I paint, but there is also a structure on the canvas, of old paint, that I use/reuse. It is so much fun and I have just started making small videos of the process.
