I agree that the use of 1st -4th corners would be helpful as such
phrases as "First corner person" can be extremely confusing. It is
amazing how difficult it can be to remember who one's FCP actually is in
the middle of a dance.
Additionally, although the term First corner means different locations
for Women and Men, in many cases you are taking about figures which are
worked around the respective diagonal so that the term First corner
diagonal is appropriately logical.
PS I would like to announce my new design for formal kilt wear. Known
as the Sobieski jacket it contains a pocket for a WAP phone, a battery
pouch for flashing light bow ties, and can be distinguished in a crowded
ball by its fine candy pink pinstripes and its sash which is draped
across the backside. The kilt to go with it is fun fur trimmed and
scalloped at the rear to give a neat bare a---d turn out. 100mm high
wedge brogues are to be worn with the ensemble.
It is available all sizes as a unisex outfit.
