[Callers] Possible new dance

I was in the MRI tube yesterday and this dance asked to be written down. To any one's knowlege does it exists? In the MRI. Imp. A1- in ring bal. Petronella, repeat; N swing A2- LLFwB; Ladies/Raven chain B1- ladies/Raven chain; P swing B2- in ring bal. Petronella, repeat; balance California twirl to new N. In the B2 you can skip the courtesy turn and make a bit lonher swing with your partner if you choose. I really don't like a lot of turning and spinning due to a personal balance issue but this felt fun. Thanks all. Mary Collins
