Divide the canvas. Tape it into three sections. Bottom = yellow, middle = orange, top = white.

Paint. Start with yellow at the bottom, let dry, then add orange in the middle. Remove tape carefully.

Sew (or glue). Place your painted piece and the plain square together, inside out. Sew around edges, leaving an opening large enough to turn right side out..

Turn right side out. Use a dowel to push out corners.

Stuff. Fill with pillow stuffing until plump.

Close it up. Use a whip stitch or glue to seal the opening.

Protect. Spray with fabric sealant if you plan to keep them outdoors.
