HELP PLEASE

I am doing the belly bands for my invites and I am doing the labeal(or seals) that will be attached. If you look in my album under diy, you can see that I have already done my monogram with just the first initial but no I want to add the last name initial as a watermark. Does anyone know how to add the watermark so it appears in each box? I know how to do a watermark but everytime I apply it, it centers itself in the middle of the page as a whole. I made the labels in the label section in Word and I can't for the life of me figure out the watermark part. I'll try to post a pic if I could find what I'm talking about.

Thanks

I wish I could help you....
