Design cushions with your own patterns and colours - a perfect outdoor DIY project. (We only painted one side of the cushion here.) Use our plain cushion covers and place a protective layer of plastic inside when decorating to prevent paint from seeping through to the back. Spray in small, precise showers using two or three colours. Let dry, then fix with an iron from the back for 3-5 minutes. You can also fix from the front, but that requires placing an ironing cloth between the cushion and the iron. Fixed paint can be washed at 40 degrees.
