METHOD: Put masking tape along the edges and apply black paint inside the tape. Let dry. Dilute white Panduro Acrylic Matt with a little water and stir well to achieve an even consistency that is slightly thinner than buttermilk. Draw paint into a plastic pipette and spray it out on the canvas with a quick squeeze. TIP! Test it out on a piece of paper first to get the correct technique and remember to protect the table and surroundings from paint spatters.
