Working on a prewashed pillowcase, sew ribbon and trim along the open edge of the pillowcase.
Following manufacturer's instructions, position the screen in the lower corner of the pillowcase. Squirt a small amount of the Bippity-Boppity Blue paint at the top of the screen in the center and at each end. Add squirts of the Oasis paint between the Bippity-Boppity Blue areas. Drag the paint over the screen using the squeegee. Lift the screen and rinse. Allow the paint to dry; then heat-set with a dry hot iron.
