Square Thru 1 (2,3,4 ...)
Start: Facing Couples
Timing: depends on number of hands to go: 1 to perhaps 6. 
Typically:
- Square Thru 1 is a gimmick
- Square Thru 2, 3, or 4 are most common

It's like doing a Right and Left Grand with 4 people but with sharp 90-degree turns before the 2nd, 3rd, 4th etc hands. 

Everyone starts with their right hand and pulls by with the person in front of them. At each stage you end up with a person beside you (who is a temporary partner until the last hand - at which time the person beside you becomes your "current" partner, ready for the next move).

To go to the next stage, you face the person beside you and pull by with the other hand, alternating hands as you go.

Square Thru 1
- pull straight by with the Right Hand
Square Thru 2
- pull by with the Right Hand (RH)
- face person beside you; pull by with the LH
Square Thru 3
- pull by with the Right Hand (RH)
- face person beside you; pull by with the LH
- face person beside you; pull by with the RH
Square Thru 4
- pull by with the Right Hand (RH)
- face person beside you; pull by with the LH
- face person beside you; pull by with the RH
- face person beside you; pull by with the LH

NOTE: there are NO turns any time you are pulling by with the LAST hand.

Note that Square Thru without giving a number is the same as Square Thru 4.
