God Bless you, my dear, for this good info :-). My feet are thanking you already..
Which Tai Chi was the teacher teaching < g r i n > who told you this about the arches, please? There are *so* many forms, 8/12 pieces of brocade, etc. Even if you ask that person and they say "Well, any form will do it," I am asking which form does that person teach?
