Hi veryskint, thank you very much for the suggestions.
Classes during the day are fine as my time is relatively flexible.
I had looked at Dance Base, but after your suggestion & looking more closely it seems like their "Iconic Ballet" (Thursday evening) and maybe "Classical Ballet Intermediate" (Friday evening) could be good (for me). (Their other classes don't seem so relevant for me - though I'm sure they are good.) So thank you - and I'll drop by there this week to see what else there is.
If anyone has any other suggestions in Edinburgh I'ld be tremendously grateful to hear them.
The Scottish Ballet/Tramway class looks ideal - but sadly a little pricey factoring in a round trip to Glasgow.
Thanks again,
Bia
