I love painting in my little sun room at this time of year. It's not too warm, not too cold. It's just right. This 24x30 linen panel is as big as my french easel will take. Any larger, and I'll have to bring my big monster easel up from the basement. And I do plan on painting larger soon.
For now I can paint, comfortably seated. Once in a while I get up and move way back to study the canvas from a distance. That's when I can see the overall picture and where to go next.
Usually I close the French doors to listen to music. My husband installed speakers that are programed to go to different rooms. So I'll shut the speakers off that go to the living room and kitchen. And I listen to the speakers in the sun room. This also comes in handy if I get the urge to paint in the middle of the night.
