I'm currently in the beginning stage of starting a new business and have been having too many opinions on my business card design and am not too sure which is which as there are just too many feng shui consultants within my group of friends and families. There has been mixed response towards a dual sided business card design and placement of my details on my business cards. 

Being the master yourself, I'm hoping i can get some opinion from you. Thanks

Haha i think you've got overly concerned over something that is NOT important in the world of authentic, classical Feng Shui. Feng Shui involves your Environment, Building, Residents and Time. None of these involves the design of your name card. Meaning - the design will NOT affect your feng shui or your luck. 

Choose something that you truly like. Choose something that you are comfortable with. Don't worry:-) 

Warm Regards,
