dress/ceremony question...

my dress is semi-cathed..and my veil is cathedral.

my alter is two steps up from the aisle...do i lift the train when i go up the steps with the handle (loop thing) on the back..or do i just walk up the step and let the train follow me..and what do i do when i sit ....do i just let the train stop where it does....and what about the veil??? do i sit on it or put it behind the chair?????

i know this may sounds strange but it is all i can think about after the rehearsal!!!

thanks.
