From any appropriate formation (there must be a center 4): The center 4 do the call in their group and move
to the outside, while the outsides work with each other and do the call as they move into the center. The
following diagrams show who works with whom on a Cross Concentric call:
The last two formations shown are really the same; the grouping on the left is used if the caller only says
"Cross Concentric..." or the Cross Concentric call doesn't start in diamonds. The grouping on the right is
used when the caller says "Cross Concentric Diamond..." or when the Cross Concentric call can only be done
from diamonds (e.g. Cross Concentric Diamond Circulate).
If the Cross Concentric call is being done from general lines or general columns, and the call starts and ends
in a 2x2 box (e.g. Cross Concentric Star Thru), the following rule applies: If the centers begin as though in
columns, they finish as though the ends of columns; if they begin in lines, they finish as the ends of lines.
If the Cross Concentric call ends in a 2x2 box but starts elsewhere (e.g. Cross Concentric Recycle from a tidal
wave), the following rule applies: The new outside dancers (the original centers!) adjust so that the long axis
of the ending formation is at right angles to the long axis of the starting formation.
