A quick tip for the guys to help control the girl keep her turns small even though she may be taking bigger steps. Ensure that the halo (or circle) you are drawing around her head during a turn (cross-body lead turns, back turns, double turns so-on-so-forth) are small. How to judge what is a good distance, the get the girl to clench her first and extend her thumb and pinky. Her hand should be held that far away from her forehead.
Another technique used often is called "catching". In a crowded situation like last time, when leading a girl into a cross body lead turn, your right hand should be ready to pick the girl up into a close hold from the count of 6. Now, this takes a little practice but this is always a good practice to do, in case you suddenly need to protect the girl from someone walking into her path. Takes a little practice with a lot of girls of different heights so that you can judge where to place your hands exactly. A good and safe area is usually just above the hip bone. From 6, your hand should be ready on 6 so the girl actually ends up spinning within your hand and fall in nicely, letting you "catch" her.
Vivir con miedo es como vivir a medias
A life lived in fear is a life half-lived.
