Paint several pieces of paper using acrylic paint, to be the foundation for your shapes. Try to use at least three differently colored sheets of paper to give the painting interest.
Allow the paint to thoroughly dry.
Cut out shapes from the painted pieces of acrylic paper. You can choose to cut out geometric shapes or more avant garde shapes.
Glue your cutouts to the canvas. Here you can choose to create a single layering of shapes for the painting's background or overlap them to create a collaged effect. Allow the glue to dry completely before proceeding to the next step.
Load acrylic paint of your choosing onto the bristles of a wide paintbrush. Add water to the acrylic paint. Pull back the end of the bristles to splatter paint over the colored shapes.
Repeat step 5 with different colors of acrylic to add depth to the painting.
