If you are having trouble painting your sky around buildings or objects while creating your painting right side up, try turning your board upside down.
Sometimes while trying to paint the sky around a house or a barn can be difficult to paint because it's further away, the strokes feel odd, it's a drippy wet sky and you're afraid of runs.
Twist your painting board around, so the sky is now closer to you. Tilt your board, so if the sky drips, it drips off the edge of the painting on onto the tape and not onto your buildings.
If you paint on a board, your painting can be twisted and turned as needed to make the brush strokes feel more natural and make it easier to paint.
You don't need to paint an entire painting right side up.
