Opinion from the fine captains here

I'll make a deal with you Roberta... if you don't mind that I removed the "laughing" emoticon from your thread title, I'll let this thread stand. For future reference, emoticons are to accentuate a title or sentence when the topic may be subject to misinterpretation. Emoticons are not for decoration.

Roberta,
You're obviously someone who understands the importance of details and making a good first impression.
My advice would be to be tasteful and unpretentious. Possibly a choral or teal color. Maybe a small anchor to show that you're in the business and it's not a card for bar pickups, but subtle enough to show that you're not coming off as "miss yachtie". Your name should be the most prominent writing followed by your phone number & e-mail, then any certifications.
