The wall knot is the reverse of the crown knot. Like the crown knot, the wall knot is of limited use by itself. However, when used is combination with other knots, the wall knot is the basis for a number of practical and decorative knots. I have shown the knot tied with three strands but it can be tied in any multiple number of strands. I find that three strands are ideal for learning this knot.
While not very exciting, the wall knot is an important step towards being able to tie a multitude of more complex knots. So take some time and learn this knot.
