Slip [Abbreviations] slp
On lead foot and slightly lowered, begin a small, left-face body rotation, rise, slide free foot back, and take weight so woman swivels LF and steps on her left foot just outside man's right foot, ending in closed position. You can imagine a cord connecting his right toe to her left toe. As he slips his foot across the surface of the floor, that motion draws her foot forward. So, it is important for the man to take a clear back step and so lead the lady's slip, but don't make it a lunge back such that you fall into a deep hole. If the man wants to turn the partnership more, say, 1/4 LF, then he will guide her to step L between his feet. This will allow him to turn LF and end in closed position. If she had slipped outside his feet, the turn would have put them in banjo, which we don't usually want.
