A wall and crown knot consists of a wall knot and a crown knot with doubled strands.[1] .The strands of the wall knot go over, under twice, and over, while the strands of the crown knot go under, over twice, and under. In the wall and crown knot they are tied in opposite directions.
This knot is often confused with a Turk's head knot, as both knots have a basket weave pattern.
