Hi Scathe,
You are probably right that you are thinking too much about it. I would advise spinning slower and as often as possible... Practice really does make perfect
What you could do is talk to one of the teachers at your regular venue, and ask them to have a look and give you pointers. Spinning is definitely not easy, and you have to keep at it...
If you ever dance on a Monday night at the Maryhill Club (Glasgow), come and see me after the Intermediate class and I'll see if I can help.
Cheers,
Franck.
