Like the name sounds, half-knot is half of a knot, a square knot to be exact, and it is a technique used often in macrame and other related fiber jewelry making.
You can use more than just the three strands of cord shown in this tutorial, but in order to keep it simple, I used just three strands, each a different color.
Begin by connecting your cords together. For the sample piece pictured, I held all three cords together and connecting them using an
overhand knot. Use a pin or tape to secure your connected cords to a work surface. I used a bulletin board and quilting pins, which are basically like straight pins used for sewing just longer.
