what you'll need
Washers, nuts, paint and brushes, clear nail polish, 0.5-mm knotting cord, tape, scissors
1.Paint washers and nuts; let dry. Seal with nail polish.
2.Cut cord into two 20" and two 12" pieces.
3.Fold 12" pieces in half and tie to washers as shown. Tape cords to tabletop to secure.
4.The 12" cords will be the bases; you'll knot the 20" strands onto them. To begin, center a 20" cord under one of the 12" cords. Bend right half of 20" cord to form a "p" shape.
5. Take the left half of 20" cord and thread it under base cords and the right half of 20" cord, then pull it through the open space of "p" in a diagonal motion. Pull both sides of cord tightly; slide knot to washer.
6. Repeat on other side: Fold left side of 20" cord over base cords, creating a backward "p" and repeat motions. Knot on alternating sides to reach desired length. Knot ends.
7. Repeat steps 4 to 6 with 20" cord on opposite side.
