From Parallel Lines with the Ends in Tandem or from Promenade (in which case designated dancers act as Leaders in Parallel Two-Faced Lines).

Ends: 1/2 Zoom, Cast Off 3/4 と Spread (to become Ends of Lines); Out-Facing Centers: Cloverleaf; In-Facing Centers: Extend, Arm Turn 1/4, と Extend.

Adjust as necessary to end in Parallel Lines.

The following illustrates the Ends part of Cast A Shadow:   Ends Cast A Shadow の前       1/2 Zoom の後   Cast Off 3/4 の後   Spread to become Ends of Lines の後 (終わり)
Parallel Two-Faced Lines から:   Cast A Shadow の前       Ends 1/2 Zoom as Lead Centers 1/3 Cloverleaf as Trailing Centers Extend の後   Ends Cast Off 3/4 as Lead Centers complete the Cloverleaf as Trailing Centers Arm Turn 1/4 の後   Original Ends Spread as Original Centers step into the vacated space の後 (終わり)
Parallel Waves から:     Cast A Shadow の前   後	Parallel 3 & 1 Lines から:     Cast A Shadow の前   後
Promenade から:(see note below):       Heads (lead) Cast A Shadow の前   Heads Step Forward as Sides bend in behind の後   Cast A Shadow の後 (終わり)

注釈:

• Ends remain Ends, Centers remain Centers.
• Cast A Shadow converts Parallel Two-Faced Lines into Parallel Waves and vice-versa.
• Ends meet with original outside hands.
• The Ends' part is
  1. 1/2 Zoom (Lead End flip away from the Center & Extend as Trailing End 1/2 Circulate to meet with original outside hands);
  2. Cast Off 3/4 (think "half, then a quarter more");
  3. and Spread (allow enough space for two dancers).
• Out-Facing Centers (the "Shadowers") should make a wide arc for the Cloverleaf so at not to interfere with the Ends. Out-Facing Centers end in the near center position.
• In-Facing Centers Extend to join inside hands, Arm Turn 1/4 with each other, wait for about two beats to allow the Ends to finish their Cast Off 3/4, and then Extend. Be sure to use only one hand for the Extend & Arm Turn 1/4. We have frequently seen overly-excited dancers step forward, join both hands, whoop and kick, and then forget which way to turn and consequently have no idea where they belong.
• When Cast A Shadow is called from Promenade, the designated Couple (Leaders) should continue Promenading until they are squared off to a wall and then Step Forward as the others bend in behind them to form Parallel Two-Faced Lines; then everyone Cast A Shadow. Executing the call in this manner guarantees that the ending formation (Parallel Waves) is squared off to the walls.

  How to dance Cast A Shadow from Promenade:

  1. If you are designated, identify yourself;
  2. Square off to a wall;
  3. Do the call.
• If all Centers start facing out, they do a Cloverleaf. If all Centers start facing in, they do their part of the call (danced as a Pass Thru & Partner Tag).
• It is considered inappropriate for the caller to call Cast A Shadow from formations in which the Ends start facing or back-to-back.
• Cast A Shadow has a tendency to expand the size of the square. Therefore, after completing the call, tighten up your formation.
