Sorry, But I am confused by what you mean. I am knitting a sweater in the round. You wrote "you also need to do a border on the sides too. basically a three row border on the top and bottom and about three stitches on either side will likely take care of the problem."
When you say a 3 row border at the top and bottom do you mean of the curling area? to frame, so to speak, the area i want to curl? and what did you mean by 3 stiches at either side? do you mean the right and left side of the sweater?
