- From double pass thru formation: Center four will Square Thru and step out of the center. Trailing couples will now Square Thru to stand behind the others. Finishes in completed double pass thru formation. Same rule for Half Square Off. On 3/4 Square Off, do the Square Thru 3/4 then Pass Thru so the new centers can do the 3/4 Square Thru.
