Start saving your salsa jars! (or any other jars). Young and old will enjoy this great outdoor project. Using a clean salsa jar with the label still intact (if you lose the label in the cleaning process cut a new label using a heavy cardstock or kraft paper) use green painters tape to cover the exposed glass on the top and bottom. Apply two coats of chalkboard spray (found at any home hardware store) on the label and let dry. Add your plant, flower or herb of choice into the jar and use chalk to write whatever you'd like on the label! Have fun!
