Hi Closer2Free,
Over time bald areas have a nasty habit of growing larger. It's a fact of life. Moving the piece back a little solves the problem in the back--at the expense of creating a problem in front. The best way to handle this is to either adjust the size of the template or make a new template. It's very common for customers to write in and say, for example, 'please increase the length of my template by 1/4 inch.' Or increase the width by xx inch. We do this all the time. Or, if you prefer, you can make a new template and send it in.
Regards,
John
