Rarely does anyone not living with the artist (and often not then either) get to see a painting in process. Most of us see it when it’s ‘ready for prime time’. On a private forum on fb called “How to Pastel” we often show process pics plus the final painting and folks appreciate it very much. So I thought my general audience might like to be ‘insiders’ too.
I often start with a drawing, and did this time as well, but got so involved that I forgot to take a pic until I had worked the top sheets for a while.

You can still see the cat drawing and some indication of where the bottom sheets will go.
I am a righty so I work my pastel, charcoal and pencil drawings from the top down and often from the left to the right to help avoid smudges.
I next worked on the sweet kitty.
And completed the dark area on the left under the top sheets. I made sure her sweet cheeks and nose were in good shape before moving on to her eyes and the rest of her face.

Then I completed the top sheets and added the darks, on the right of the kitty, under them.

Then I spent some time creating the bottom sheet and making sure my shadows were properly done to create hills and valleys. And then waited a bit, sent it to my favorite crit person and photographed it this morning in natural light.
