Thanks to all for the useable feedback.

I have noticed that a kind of intution takes over as the forms are repeated, each day subtle adjustments are made almost without effort. Anybody else feel this?

After Knees, I must ask about Feet ...

I do SFQ barefoot, on carpet (soft and warm), is that good, better or best?

Also, I read/heard that we should practice with the Sun behind us, I've not seen this anywhere else mentioned so maybe I'm wrong.
At night I put my back to where the Sun is going to rise the next day, is this part of the Art of Qi Gong or am I going to uncessary lengths?

Many Thanks
