I am teaching a couple that has never danced before Bacahata for their daughter's upcoming wedding. I taught them the Basic, Progressive and Box steps to start. I had them go palm to palm to transition from Basic to Progressive and return to closed position right before returning back to Basic. They then asked how to signal a transition from Basic to Box step and I had no answer. The sticking point is count #3 where the leader goes FWD Left instead of to the side. I hope the description is understandable. Can you help?
