With the open-ended side of the burlap pouch facing down, glue or sew on eyes, a nose and a mouth. If you cannot find a premade burlap pouch, sew one together using burlap. Set aside and let glue dry.
Open up the burlap pouch and layer in 1/8 inch of potting soil. Sprinkle in grass seeds. Then fill up the burlap pouch full with potting soil. Close the burlap pouch shut using a rubber band or tie.
