Small pieces can be used as plant markers. The only other items needed are wire coat hangers, permanent marker, gloves, and some strong wire cutters, if you have them.
I've tried 2 different methods of making the markers and each was equally easy. The first method is to twist the wire in a squiggle and insert a piece of terra cotta into the free formed holder, the second way is to grasp the terra cotta piece and wrap the wire around it. Write the plants name on the terra cotta piece and place the marker in you garden.
Be well and happy gardening!
