Dressing
Arranging rope with the fingers so that wraps lie evenly, without twists and with even tension; in general knotting, dressing a knot means arranging its parts neatly before loading.
Shibari Study’s glossary describes dressing as working the rope with the fingers so the wraps lie evenly, without twists, and with balanced tension. It considers dressing most important in suspension, where rope that carries load has to sit in the right place on the body. The same word is used in general knotting, where a knot is dressed by arranging its parts neatly before it takes load; Wikipedia’s knot article names how a knot was dressed among the factors that affect its tested strength, and advises dressing a knot cleanly and then tightening it to reduce slipping.
