Wet on Wet

• Tape the edges of a piece of watercolor paper to a flat, smooth surface, such as a piece of plexiglass or a solid-surface countertop. Spritz it with a spray bottle filled with water. Apply watercolor paint to the wet surface with a paint brush. The paint will bleed and spread. Allow the paint to dry and repeat.
  
  

Spray Art Textiles

• Use a spray bottle to create colorful, splatter-printed textiles that can be used to make pillow covers and home decor items. Fill a spray bottle about half full of warm water. Pour a 2-ounce bottle of acrylic craft paint into the bottle and shake it to dilute the paint. Spray the surface of a pre-washed piece of white, 100 percent cotton fabric. Add more water if it doesn't come out of the nozzle smoothly or if you prefer thinner paint. Rinse the bottle and nozzle immediately in soapy water. Lay the fabric flat to dry and wash on a gentle cycle and hang to dry.
  
  

Keep Paints Workable

• Acrylic paints are usually fluid and flexible, but they can dry up quickly. And once acrylic paint has dried, it becomes hard and impossible to use. To keep paint on a palette workable, mist it with a spray bottle filled with water.
  
  

Resist Paintings

• Apply strips of masking tape to a primed or painted canvas -- make a random design, a predictable pattern, or write words -- and spray the entire thing with a spray bottle containing acrylic paint that has been diluted with water. Allow the paint to dry and remove the tape to reveal your design.
