Dos:

• Do a professional design and print it professionally as well, not at home. Remember that a business card is your first impression, and those are the ones that last longer.

• Make sure you’ll be including your contact info.

• Always include your blog or Web site address, even if it’s only out of curiosity, they’ll visit it.

• Place key factors and interesting stuff about yourself.

Donts:

• Too much info, this will definitely confuse the reader.

• Print the info on one single page, don’t lose valuable space.

• Using low quality images will be printed with pixels.

• Readable fonts. Don’t use more than 2 font types per business card design.

• Bad quality paper.

• Using a rainbow of colors.
