Well, I haven't looked at your macro, but if you kept a list of where the 
seams are on the row below (as an array), you could use those numbers to 
'repel' seams on the current level.  Alternately, if it's easier, you can 
mark the centers of the stones on the row below and use that to 'attract' 
the seams on the current row.

An even better way would be to use a 2D array of numbers and just layout the 
seams in the array, making sure that the consecutive layers don't have seams 
at the same places.
