    Start with a closed cord loop

    Place a loop of thinner cord beside the host rope. Keep its joining knot outside the wrap band.

    Carry the closed upper bight around the host rope.

  3. 3

    Add a second wrap

    Continue in the same direction, keeping the strands aligned.

  4. 4

    Add a third wrap

    Lay the next turn alongside the earlier turns.

    Complete four wraps

    Keep the lower bight free beneath the turn band.

    Bring the upper bight down

    Bring the upper end around the outside of the coils to meet the lower bight. Do not pass it through the lower loop.

  7. 7

    Gather the wraps

    Arrange the four doubled wraps together. Keep both end bights below the band for the shared locking connector.
