what knot do you use for lacing
When tying the half-knots, a right-over-left half-knot followed by a left-over-right half-knot (or vice versa) forms a square or reef knot, a fairly effective knot for the purpose of tying shoelaces. However, tying two consecutive right-over-left half-knots (or two consecutive left-over-right half-knots) forms the infamous granny knot, which is much less secure.
