Monograming three initials?

In a monogram the last name is the middle initial with the other two first on the left and then on the right. So, it would be ABG, with the middle letter significantly larger than the other two --- BUT - if you are ordering from a company, call them to find out what order they want the initials - some places would ask you to specify the order, other may not. Find out from whom you are ordering how it should be.
