Cord and Twine: The technical difference between cord and twine is that cord is made with fibers spun in a counter-clockwise direction. Twine is made with fibers spun in a clockwise direction. In my pattern directions I usually refer to "cord" as a general term meaning any long stringlike material.
Focal Bead: A big beautiful bead that takes centre stage in your finished jewelry.
Fillers: (Also called anchors, knot bearers, carriers or bead carriers) In macrame, each strand or cord is a knotter or a filler. The fillers are the cords in the middle that the knots are tied around. They do not move when manipulating the cords to make the knots. See Fig. 1 on my Half Knot Instructions page to see an example.
Half Knot (HK): A basic macrame knot using 4 cords. The outer 2 cords are "knotting" cords, or "knotters", and the inner 2 cords are "carrier" or "filler" cords. If a pattern says to use a "half knot", and doesn't specify right or left, it doesn't matter which one you make.
Knotter: In macrame, each cord is either a knotter or a filler. The strands of cord or twine you use to make the knots are called knotters.
Lark's Head Mounting Knot(LH): This knot is commonly used in macrame to mount cords to a dowel or ring. This knot can also be used to mount hemp twine or other cording to a bracelet or necklace clasp, keychain ring, or cell-phone strap. 2
Left Half Knot (LHK): A half knot that is made by bringing the left hand carrier cord across the filler cords first.
Left Square Knot (LSK): A square knot made by making a left half knot, then a right half knot, in that order.
Right Half Knot (RHK): A half knot that is made by bringing the right hand carrier cord across the filler cords first.
Right Square Knot (RSK): A square knot made by making a right half knot, then a left half knot, in that order.
Overhand knot (OH): The most basic of all knots, this is essentially a half knot using only one cord.
Switch Knot: The term switch knot refers to switching the knotter and fillers with each other, thus forming a decorative transition knot. This also allows you to save some cording because your (usually) longer fillers become the knotters.
