Start assembling the legs of your flower pot person using the 8-inch clay pots. Tie a knot in one of the ends of the rope or wire. String a styrofoam square onto the rope or wire and push it down so it rests on the knot. If necessary, tie another knot in the rope or wire. Now slip the untied end of the rope or wire through the hole in the bottom of an 8-inch clay pot, going in through the inside of the pot and out through the bottom of the pot. The styrofoam square should rest against the bottom of the pot on the inside.
