Designate ones and twos, then have each set turn 1 quarter to the left for Becket. Then verify that all the ones are on the same side. Ones progress leftward & down the hall.
It may help to walk through a colonnade once without arches, to demonstrate the paths, then add the ones' arch (left to left!)
Give the twos a chance to practice arching the colonnade during the walkthrough.

Left Colonnade: ones join left hands to make an arch and hold that arch for the entire figure. Ladles trade positions by left-shoulder pass through with ladle two going under the arch (and the arch moves!). Gentlespoons trade by left shoulders with gentlespoon two going under the arch. Ladles trade back by left shoulders; gentlespoons trade back by left shoulders. Each trade has 4 beats of music, so there's no need to rush.
