Yeah!  I managed to fit in painting my Burnt Sienna ground on my new canvas.  I apply a very thin layer of Burnt Sienna diluted heavily with mineral spirits with a soft brush.  Then I use a clean soft terry cloth to rub it all in and remove any excess.  I’ll give it a couple days to dry completely.   Then it will be ready for me to begin my first thick layer of my underpainting.

Here is a visual process of getting the canvas ready.
