Rescue pickle jars or other glass containers from the recycle bin, and give them a new purpose holding cotton products. To accommodate the knob, drill a hole in the center of the lid. Prime and paint the lids, and let dry. Spray with a clear sealer to protect the paint. Once dry, attach each knob, and cut off the excess shank. For a final pop of color, glue strips of punchy patterned paper to the jars.
