Most contras with "Petronellas" also have role-specific figures like swings and courtesy turns which are challenging in a group of mostly beginners. But Petronellas are easy and everyone likes them, so here's a dance any group can enjoy (above age 7 or so), without worrying about roles.

The two-hand turn in B2 gets everyone back on their original side, and opening out to face the next couple leads smoothly into the circle left.

For Ian Brehm, a founding member of the Philly teen dance, whose enthusiasm, personality, and across-the-board contributions were hugely important to making the series thrive. Thanks, Ian, for being always On the Ball!
