1 half passing = put up the pin at the next point, twist both pairs twice, but without enclosing the pin, and pass the inner left thread over the inner left one = twist the two pairs again = cross as before and so on.
Valenciennes ground (fig. [796]).—The Valenciennes ground is formed of little plaits for which 2 pairs of bobbins are used. These plaits are often used in other kinds of lace as well, as may be seen for instance in figs. [801], [802] and [806] which are not Valenciennes patterns.
Fig. 796. Valenciennes ground.
According to the size of the squares the plaits are made with either 4, 6 or 8 half passings, 2 pairs of bobbins being invariably used. The plaits are joined by a half passing, made with the last pair of the left plait and the first of the right = stick the pin into the hole = enclose the pin by a half passing and work the next plait on the left with the two left pairs and the next plait on the right with the two right pairs.
Brussels ground (fig. [797]).—For the sake of greater clearness, this ground too has been worked and reproduced here on a magnified scale.
