From facing lines: Center two in each line do a Partner Trade and step forward out of the set as the Ends Crossfold to move in behind them. All now do a Cloverleaf to half sashay as they meet the other dancer and complete the Cloverleaf movement. Trailing couples (after the half sashay) will do an Outsides Out. Finishes in facing lines.
