Plant hangers come in various materials and sizes but are all constructed with the same idea in mind: to be sturdy enough to hang a plant and its pot and allow enough room for the plant to grow out around the hanger. The materials that are used should be strong but lightweight and flexible to allow for movement in the breeze and ease of use.
Determine the lengths of wire or cord that will be used in your hanger by first deciding how long the planter will be. This should be the measurement from the place that the planter will be hanging from down to the bottom of the plant's pot. Multiply this measurement by seven. This will determine how long each cord should be. Cut eight cords to this length.
Line all of the cords up so that the ends are together and fold the cords in half so that all ends meet evenly.
Grasp the center of the cords and feed it through the ring, forming a loop about four inches long.
Feed all of the ends of the cords through the loop and pull the cords tightly, forming a knot around the ring. You should now have 16 cords of even length hanging down from a knot on the metal ring.
Separate the cords into four groups of four strings. If desired, braid or tie macrame knots down each strand of strings in a decorative manner to the desired length of the top section of the hanger.
Measure the circumference of the plant pot that will be used for planting. Use this measurement to determine the length of the top section of the hanger. Mark the end of the top section -- at this measurement -- with a double knot in each of the four strands. So if the plant pot has a circumference of 18 inches, the knots should be located 18 inches away from the metal ring.
Separate the strands, collecting two cords from one strand and combining it with two cords from the next nearest strand. Tie a double knot in each of the four newly formed strands approximately three inches below the previous knots.
Separate the strands again, collecting two cords from one strand and combining it with two cords from the next nearest strand. Tie a double knot in each of the four newly formed strands approximately one to two inches below the previous knots.
Tie all of the strands together at the final desired length to form the bottom support for the plant pot.
Trim the remaining hanging cords to a desired length to form a bottom fringe.
