Square Around is an old call written by Don Beck (a Massachusetts caller, who also authored several other calls, including Ferris Wheel).

From an Eight Chain Thru:

Centers do your part:

Square Thru 2; Ends Bend; Square Thru 3.

Ends do your part:

Right Pull By; (Concentric) Left Square Thru 2; Left Square Thru 2.

Ends in Back-to-Back Lines.

Everyone does a total of 5 hands.

When used with "parts" concepts such as Initially or Finally, each Pull By + the following 1/4 In or Ends Bend counts as one part.

Clark Baker likes to think of Square Around as a circular kind-of Square Out.
