I'm the in-house Creative Services Manager at the National Strength and Conditioning Association (NSCA). At our yearly National Conference, we hosted a formal reception for recipients of our most prestigious credential, RSCC (Registered Strength and Conditioning Coach). The invitations needed a very formal, wedding like feel to them as this is an elite honor. I went simple with black and white and elaborate calligraphy on a two-sided colored paper from Neenah. I went with a gate fold so I could get stickers made of our strength and conditioning Oscar-like statute made to seal them shut. I love the simplicity and elegance of the design.
