Two questions:
1.) I'm printing my invties at a local printer. Is 80# cardstock fine to use for invitations? They gave me options and I'm okay with 80#, but have people tried it and just didnt like the final product? Should I spend the extra money on an even thicker piece?
2.) When addressing invites, do I have to use their "full" first name if they've gone by a shorter name all their life? Example: Shelly's first name is technically Michelle, but always goes by Shelly. David has NEVER gone by David, just Dave.
