Okay, seriously...same pastor, same dress store, SAME NUMBER OF BRIDESMAIDS...lol. We really are gonna have the same wedding. ;) jk.
Are you gonna have scripture readings during the ceremony? The 2 girls who I really wanted to have as bridesmaids (but just couldn't afford it), I'm going to have read scripture (or another reading). I don't think guestbook is a bad job, but if you wanted something a little more va-va-voom, maybe a part in the ceremony would do the trick.
