|A1:||Heads link elbows to make a line of three. Advance and retire; advance again and women change lines before the line retires. (Pass right shoulders in theory.)|
|B1:||The middle person in each line (nominally the man) does a right elbow swing with the person on the right, then a left elbow swing with the one on the left.|
|B2:||Reels of 3 along the lines (the middle person starts by giving right shoulder to the person on his/her right). At the end of reel the middles hastily move to the next line on the right..|
There's an 'Easy Twelve Reel', adapted from this one, archived on Brian Scowcroft's square sets page. He says he sometimes adds two more figures: C1: All circle left (16 steps). C2: Trios form baskets of 3.
N.B. You'll need 48-bar tunes for that version.
Thumbnail: Square of threesomes. Forwards and back, repeat swapping ends, middles elbow swing, reels, middles move round.
