Now I'm a bit confused.
As i see it, For the 18 St's on needle #2 only, you continue to follow the sequence of the leg pattern 1-12, if the last row you did was row 11, then next one is row 12, then back to 1,2,3,4,5, in order, needle 1 & 3 are stocking stitch with the gusset decreases.
or do you mean you have done cable crossing on row 11 and the next 5 knit rows? in that case, yes do row 5 cable cross row.
