- From double pass thru or completed double pass thru formation: Lead dancers Quarter In as trailers Quarter Out (like a Zig and Zag) then arm turn 3/4 with adjacent dancer to form a new pair of lines (with centers facing one way and ends facing opposite). New centers now do a Crossrun. Double pass thru formation finishes with lines facing in and completed double pass thru finishes with lines facing out.
